Dear FreeSurfer Users,

I sent an email to this maillist a couple of weeks ago asking help for the error that I encountered after running 'recon-all -s ${Mysubject} -hippocampal-subfields-T1' with freesurfer 6. The content of this email is attached below. Since then, my colleague and I have been working on figuring out where the error is from, but we got two more questions here:

First, is it possible that we can set the tmpdir to /tmp or something else globally? How can I do this?

Second, is it possible to fix test for '-e/scratch' to test for '-dw/scratch', which is a directory writable by current user?

Any comments and suggestions are appreciated. Thanks in advance!

Previous email: I was trying to segment hippocampal subfields using FreeSurfer 6 with data that have already undergone the FreeSurfer 5 pipeline recon-all -all. According to the usage described on the webpage of HippocampalSubfields (http://surfer.nmr.mgh.harvard.edu/fswiki/HippocampalSubfields), I ran the command: recon-all -s ${Mysubject} -hippocampal-subfields-T1 Then the following errors occurred. It seems that the program 'segmentSubjectT1_autoEstimateAlveusML (line 113)' was trying to make a directory in a Read-only place. But the error message did not indicate where this place was. I have tried to look codes in 'run_ segmentSubjectT1_autoEstimateAlveusML.sh" . But it does not have this information either. As segmentSubjectT1_autoEstimateAlveusML is a binary file, I could not dig out any more info. Does anyone know how to solve this error? Or know where the program was trying to mkdir?
