[Freesurfer] Checking optseq efficiency of a custom par file.

Dear Freesurfer list,

Using the optseq2 program, is it possible to calculate the efficiency of a custom par file? I have an fMRI task that will be split into three blocks. I want to calculate the overall efficiency of my overall design byconcatenating the best par file from optimizing each individual block. I have already tried doing so by concatenating the three par files (updating the onset times) and inputting this into optseq2 by:

...

optseq2 --in new_file.par --nosearch --tr 1.75 --ntp 1080 --psdwin 0 3.5

1.75 --o new_dir

If I do this, however, I get a "core dump" error. Does anyone know how I might going about doing this? I've attached the new_par file for convenience.

Best, sam
