Minimum system requirements
GRIDCOR needs a PC running with Windows 95 or newer versions (Win98, Win Me, Win XP), Win NT 4.0 or newer (even Win 2000). It must have 32MB of RAM and 10 MB of free disk space.

Shareware and copy protection
GRIDCOR is shareware: it can be freely distributed as long as it is not modified in any way.

However, it has a copy protection system that restricts to five the numbers of times you can run it.

Once you have used it five times, GRIDCOR halts to give you a registration code and ask for a register key. If you want to keep on using it, you must get in touch with the Centro de Terapia Cognitiva by fax (34.93.455.21.76), phone (34.93.456.83.16) or email, purchase the program, give them the code and get the register key.

How to install GRIDCOR

  1. Click here to download the demo version of GRIDCOR.
  2. Once you’ve got the program, doble click on GRIDCOR.EXE. This will bring up this window:

  1. Click on next; now you must choose the directory where you want to install GRIDCOR. Default directory is «C:\Program files\Gridcor». If you want to change it, click on browse and go to the desired directory:

  1. Now, you have to choose the name of the folder which will be added to your windows Start toolbar. To change it, write the desired name in the space provided:

  1. Now, the installing program is ready. Click on install to start copying files to your hard disk. You can cancel it, or go back to change the parameters:

This bar shows the progress of the installation:

  1. This window is displayed once the installation is over. Click on finish to close it.

Sometimes, according to your system configuration, you will have to restart the computer.


Trial and License

The first time you run it, GRIDCOR pops up this window:

Here you can see the number of runs left. If the program is not registered, you may use it up to five times. Each time you run it, it will substract one run from this limit and show this screen again.

Once you’ve ran out of the number of executions allowed, the application shows this dialog box:

By clicking on No you close the program. After clicking on Yes, GRIDCOR displays this window:

The text in blue is the information you need to get in touch with the Centro de Terapia Cognitiva to purchase GRIDCOR and get the register key.

The text in red is the registration code that unlocks GRIDCOR only on your computer. You must send it exactly to the Centro de Terapia Cognitiva.

After the purchase, the Centro de Terapia Cognitiva will send you a register key to unlock GRIDCOR on your computer. You must write it exactly (or copy and paste) on the field at the bottom of the dialog box, and click on License. GRIDCOR will give you a confirmation code, and exit to save the registration information.

If, for any reason, the key failed, you may ask the Centro de Terapia Cognitiva for a registration diskette. Again, after checking out the purchase, the Centro will send you this diskette by snail mail (you don’t need to give us the code). With this diskette you may unlock the application once. This diskette cannot be copied. You have to insert it in drive (A:) and click on Import from Drive A:

Once the application has been registered, it will show this window the next time you run GRIDCOR:

How to analyze grids

This is GRIDCOR’s main menu:

When no grid file has been created or loaded, the button 3.- Statistical analysis is disabled. To analyze an existing grid, you need to load it first with 2.- Load/Modify data file.

How to create a new grid file

To create a new grid file, click on 1.- New data file.

Grid file Parameters

This window will immediately appear:

  • Títle of the analysis: The name you want to appear on top of the analysis; not the name of the grid file. Commas are not allowed on this field.
  • Number of constructs: Up to 50 constructs; if you use more than 20, you will need more than one page to print the summary of scores. By default, 20.
  • Number of elements: Same as above.
  • Maximum Score – Scale range (1-9): the maximum value of the Likert scale (up to nine). By default, 7. For dichotomous grids, enter «2» and use «1» and «2». You can use ordinal scales up to nine elements (by entering «9»).
  • Simulated data (Y/[N]): GRIDCOR may generate a random data matrix which may be useful for research purposes.

Entering the data

This is GRIDCOR’s data entry matrix:

On the first line is the name you gave to the analysis. Next there is the grid data matrix itself, with the labels of the left poles of the constructs at the left of the data cells, and the right ones at the right. To each column belongs a letter, which appears again at the right of the window with the labels of the elements.

Warning: the «self» must be the first element (letter A), and the «ideal self» the last; otherwise, the cognitive measures involving these figures will be wrong.

If you have not chosen to get a simulated data matrix, the cells for the data and labels are empty.

You may move around the screen in the usual way (with tab and cursor keys, etc), and fill the cells just like any worksheet application. With «RETURN/INTRO» at the end of each line of the data matrix, the cursor will move to the beginning of the next.

The constructs and elements labels may have up to nine characters, so it may be neccesary to condense the original labels.

  1. when a construct (or element) is monotonous (that is, has the same score in all its cells), or
  2. the scores of two constructs or elements are identical,

it becomes imppossible to make the proper statistical analysis, and GRIDCOR halts with an error message. It is a good idea to ensure, before entering the data, that no element or construct has monotonous scores and that there are not two identical elements or constructs. In that case, you must not enter the monotonous construct or element, or at least one of the constructs or elements which are identical.


Hint: It is a good idea to write the construct labels in small letters and the element labels in capital leters, in order to distinguish them better on the printed output.

Saving the data

Once you have finished entering the data, you must save them into a data file before starting the analysis. Clicking on Guardar will display this window (it may be different according to your operative system):

Now you must enter the name for the data file. When you click on Guardar, GRIDCOR adds to this name the extension «.dat» (for «GRIDCOR data file»), closes the window and returns to the data matrix screen.

Warning: on some computers, it is neccesary to save all data files (*.dat) in the very same folder whete the application is located (C:\Program files\Gridcor); otherwise, GRIDCOR may pop up an error message.
The grid data file»*.DAT» GRIDCOR saves its data on ASCII (DOS text files). These files may be opened and edited with any word processor. You don’t need to open «*.dat» files to analyze grids; but it may be useful to do it, for instance, to directly copy the scores to another text, or to change them without using GRIDCOR’s data entry menu. You have to save the file in the same ASCII format.
As you can see in this sample file, the first line contains the number of constructs (10), of elements (13) and the maximum scale range (7), separated by two spaces each. The second line is the title of the analysis. Next is the data matrix itself, and the labels: first, the element labels, then the labels of the right poles of the constructs, and finally the left pole ones.

If you want to change the parameters of the analysis, (number of constructos and/or elements, maximum scale range, title) click on Modificar.

To start the analysis, click on Cerrar.

Analyzing grids

Now that you’ve saved a grid data file (or if you’ve loaded an existent one), the button 3.- Statistical Analysis is enabled.

Click on it to start the analysis. After a few seconds, GRIDCOR will pop up this dialog box:

Now you must choose the minimum value the Pearson’s r between two constructs must reach to consider them associated and, therefore, able to form an implicative dilemma. By clicking on Yes, you will choose the r = 0.20 criterion; with No, the r = 0.35.

Hint: It is recommended to use the r = 0.20 criterion because this will detect more dilemmas. You may later choose the ones with higher r’s.

The status bar will show the progress of the analysis, which may take a few minutes according to your processor’s speed, the size of the grid and the speed of the disk where the data file is.

Once it has finished, GRIDCOR automatically saves a brief results file, with the same name as the data file that has been analyzed and the *.lis extension. On this file you will find:

  1. Focused grid
  2. Summary of cognitive measures
  3. Self-definition and discrepancies
  4. Eigenvalues
  5. Plot of axes 1/2 (joint graph of axes 1 and 2)
  6. Dual diagrams (independent plot of axes 1 and 2)

However, GRIDCOR offers many more grid measures which you can display on screen, save and print. You may choose the ones to save into a complementary report file (with the *.res extension).

This is the grid scores menu:

You may close it and return to the main manu by clicking on Close.

Saving results

The 7.- Save to disk button displays this window:

You may select the measures you want to save to the *.res file by activating its checkboxes. By clicking on All Analysis you may activate all checkboxes, and on Complementary Report, only the measures that are absent from the automatically generated report (the *.lis file).

When you click on Save, GRIDCOR saves all selected measures into a text file, with the same name of the grid data file and the *.res extension. You may open and edit this file with any word processor.

Warning: the printer buffer may overload if you choose to print all measures. It is a good idea to select only some of the measures to save, because a *.res file too big might generate an error. You may repeat this process by saving the measures you left out on the first time in files with different names (also with the *.res extension).

Printing the outputs

To print the results of the analysis you must have saved them into a complementary file (*.res) or print the automatically generated file (*.lis).

Warning: As said before, the printer buffer may overload if you choose to print all measures. It is a good idea to select only some of the measures to save, because a *.res file too big might generate an error. You may repeat this process to save the measures you left out on the first time.

The 4.- Print file button displays a window where you can select the results file to print

Once you have made your choice, GRIDCOR shows this screen:

Here, you can have a preview of the printed output. You may even modify this output by writing directly inside the text box. To send it to the printer, click on the printer icon on the upper right of the screen.

You may also copy the results into a word processor file. First, select the results to copy, placing the cursor over them and moving the mouse while pressing the left button; then, press the [Control] and [c] keys. Now, open the word processor and place the cursor where you want to introduce the results, and press [Control] and [v].

Warning: Sometimes it will be necessary to fix the copied text, specially by removing extra spaces in order to align the columns. It is better to copy the Dual Diagrams and the Plotting of Axes directly from their windows, not from the results file.

You may return to the main menu by clicking on Close.

Displaying results on screen

Once you have analyzed a grid, you may display the results on screen. GRIDCOR will show you this menu:

Most of these windows have only one button, Close, to return to this same menu:

Some other windows have tabs to display different kinds of data; this is the case of the Coordinates and Contributions window, where you can look at the construct’s or element’s coordinates:

Interactive displays

Some of GRIDCOR’s dialog boxes allow you to choose the kind of data to display, print or save.

Dual diagrams

The 3.- Dual Diagrams button displays this window:

You may select the axe (factor) to plot by activating its radio button. Once you have made a selection, you may save the graphic into a file (with the *.sim extension) or print it.

You may also paste the axe into a word processor file following the same procedure as with the Printing results menu. First, select the results to copy, placing the cursor over them and moving the mouse while pressing the left button; then, press the [Control] and [c] keys. Now, open the word processor and place the cursor where you want to introduce the results, and press [Control] and [v].

By clicking on Close you can return to the results menu.

Plotting axes

The 4.- Plotting of axes button displays this window:

Here you can look at the joint plot of the first two axes (factors), with the constructs in blue and the elements in red. This display may be modified in several ways.

  1. If the Labels checkbox is activated (as above), you will see the labels of the constructs and elements; otherwise, you will only see its locations. The blue «0» are the constructs, the red «*» the elements:

  1. When the Labels checkbox is not checked, you may display separately each element and/or construct with the Show buttons. Just choose from the appropriate drop-down menu the construct (left menu, in blue) or element (right menu, in red) the display and then click on Show. The label of the construct or element will appear; in the example below, the SELF element (upper left part of the screen):

All constructs and elements may be displayed, one by one, this way.

  1. The Show Constructs and Show Elements buttons display all the construct or element labels.
  2. The Blank screen button cleans the screen leaving only the crossing axes:

  1. The Save button saves a file with the particular plotting of axes you have created. This file has always the same name, EJES.SIM, and is always saved where the grid data file (*.dat) is.
  2. The Print button sends the graph to the printer.
  3. To return to the previous menu, click on Exit.

Cognitive measures

The 6.- Cognitive Scores button displays a new menu with a variety of measures:

The 7.- Global Scores displays a window with a summary of the most important measures of the grid:

Most of these windows have only one button, Close, to return to the cognitive measures menu:

Implicative Dilemmas

You may look at the implicative dilemmas of the grid by clicking on 0.- Implicative Dilemmas. If the grid does not have implicative dilemmas, GRIDCOR displays this dialog box:

Otherwise, the dilemmas are displayed in this window:

Hint: Click here to learn more about the implicative dilemmas.
