Defaults


Defaults are specified in icatb_defaults.m file. The following are the main variables involved in GIFT and EEGIFT:

Colors
Colors are RGB values i.e, [0 0 0] means black. Background color can be changed by changing variable values. The variable names are listed below for figures and user interface controls:
Fonts for user interface controls
UI_FONTNAME - font name.
UI_FONTUNITS - font units.
UI_FS - font size.
Display Defaults
Display defaults in display GUI can be changed by accessing defaults like:
DETRENDNUMBER
Detrend defaults can be changed by changing the variable DETRENDNUMBER value. Options are 0, 1, 2 and 3.
Smoothing parameters
When SMOOTHPARA variable is changed to 'Yes' the time courses are smoothed by the value indicated in the variable SMOOTHINGVALUE.
FLAG_ACKNOWLEDGE_CREATORS:
FLAG_ACKNOWLEDGE_CREATORS variable used to display acknowledgement for creators. You can turn off the dialog box by changing variable to 'off'.
ICAOPTIONS_WINDOW_DISPLAY:
ICAOPTIONS_WINDOW_DISPLAY variable used to display ICA options window. You can turn off the figure window by changing variable to 'off'.
STORE_DIRECTORY_INFORMATION:
When STORE_DIRECTORY_INFORMATION variable is changed to 'Yes', directories specified in cell array DIRS_TO_BE_STORED are stored in the file selection window.
ZIP_IMAGE_FILES:
When this variable is set to 'Yes', the component images will be compressed to a zip file based on their viewing set.
METHOD_ENTERING_REGRESSORS:
Variable has three options like 'AUTOMATIC', 'GUI' and 'BATCH' for temporal sorting. Each option is explained below:
FLIP_ANALYZE_IMAGES:
Flip parameter for the analyze images. Default value is 0.
NUM_RUNS_GICA:
Number of times ICA will be run. Default is 1.
DEFAULT_MASK_OPTION:
Mask is calculated by doing a Boolean AND of voxels that surpass or equal the mean. By default first file for each subject is used. You can use all files by changing variable value to 'all_files'.
OPEN_DISPLAY_GUI:
Option is provided to open the display GUI automatically after the analysis. You can turn off the option by changing variable value to 0.
CENTER_IMAGES
A value of 1 means subject spatial maps will be centered based on the peak of the distribution.
PREPROC_DEFAULT: Data pre-processing default.
1 - Remove mean per time point
2 - Remove mean per voxel
3 - Intensity normalization
4 - Variance normalization
PCA_DEFAULT - PCA default.
1 - Standard
2 - Expectation Maximization
BACKRECON_DEFAULT: Backreconstruction default.
1 - Regular
2 - Spatial-temporal Regression
3 - GICA3
SCALE_DEFAULT- Scaling components default.
0 - No scaling
1 - Percent signal change
2 - Z-scores
