 Since data collection is not very useful without subsequent analysis, we have tried to make CIGAL directly compatible with fMRI image analysis software. CIGAL output files have always been directly readable by our own in-house image analysis programs and it now provides interoperability with other software. For example, CIGAL can now be configured to automatically generate output files describing stimulus timing in the 3-column format used by the FSL analysis package (Smith et al., 2004), in detailed stimulus-response events in the XML format being developed by the FBIRN project (Gadde et al., 2004), and/or as trial event tables suitable for import into spreadsheet or database programs. Support for other formats could be added with very little effort. Since data collection is not very useful without subsequent analysis, we have tried to make CIGAL directly compatible with fMRI image analysis software.

 +===== Running CIGAL simultaneously with other behavioral software =====
  
 +If you already have your behavioral tasks set up using other software (e.g. EPrime, Presentation, Matlab, etc.) you can run that software for task stimulus and button response recording, and run CIGAL simultaneously to record synchronized physiological and eye-tracking signals.  This works well provided that your computer has 2 video monitors so that each program can be run on a different screen. In that case you can run CIGAL on the secondary monitor while you run your regular behavioral software on the primary monitor. Both programs can be automatically triggered by the scanner so that they run in synchrony. You (and your subject) will see your task stimuli displayed on the main screen, and you can watch the physiological and eye-position signals displayed simultaneously in real-time on the second screen. CIGAL uses almost no computer time for its data recording and very little for its display; running on a modern dual-core computer CIGAL has no significant impact on the timing accuracy of the other program.
