[Freesurfer] Error with recon-all: You are trying to re-run an existing subject

Hi All,

I'm trying to use recon-all on some structural data, and when I drop the command (specifically, recon-all -i /cluster/iaslab/SPAR/mri/recon/3danat/003/001.mgz -subjid SPAR_016_130708), I get this error message:

ERROR: You are trying to re-run an existing subject with (possibly) new input data (-i). If this is truly new input data, you should delete the subject folder and re-run, or specify a different subject name. If you are continuing an analysis of an existing subject, then omit all -i flags.

I have tried all the options suggested in the error message, and none work. I can't delete the subject folder, because no such folder exists. I tried running the command with a different subject name, and although the command appeared to complete without error, no folder with the new name was created, and no files were generated. I tried removing the -i flags, and I got this: ERROR: nothing to do.

Any suggestions?

Thanks, Joe Andreano
