Hi
I have recorded Cardiac and Respiratory dataon GE 3T scanner.
Files I get from scanner are:
Filename                                                                                             No_Datapoints
PPGData_epiRT_0703201816_24_42_498                               148419
PPGTrig_epiRT_0703201816_24_42_498                                 1411
RESPData_epiRT_0703201816_24_42_498                             37105
RESPTrig_epiRT_0703201816_24_42_498                               385

Q1:
I tried to run the GE batch file example with the Data files. I changed TR, Number of slices, total volumes. I was not sure what 'Nslicesperbeat' meant , i left field empty.
Here is the output error.

Q2. How to use these Trigger info files?
