Dear FreeSurfers,

Our group has encountered an error while unpacking the first set of data we acquired on Bay 2 since the upgrade.  Here’s our command line:

unpacksdcmdir -src 07120620/ -targ . -generic -scanonly SUBJ.out

We then modify the .out file from

10 epzshim_cjw02_nonalternat bshort f

and save as SUBJ.cfg

Next command line is: unpacksdcmdir -src 07120620/ -targ .. -cfg SUBJ.cfg -fsfast

We get this error when it encounters the first functional run:

---------------------------------------------------------
Run 9 -----------------------------------------
Mon Dec 10 12:43:27 EST 2007
9 epzshim_cjw02_nonalternat bshort f
ERROR: mri_convert
child process exited abnormally

We’ve re-run the second unpack command after putting different functional runs (or even single functional runs) in the first position processed, and the same error message occurs each time.  We’ve also tried the process on functional runs that do not have a z-shim (thought that might be causing trouble), but the error still comes up.

Any ideas?

Thanks in advance.
