Hello,
I am also trying to use mkheadsurf and getting the same errors described in the January topic by user Yong-Jun Lin.

MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg71781.html

1. The first error message is "subjdir: Undefined variable.".

I followed the thread and also manually defined subjdir

2. Same problems with

mris_smooth -n 10 -b /..

resulting in error: MRISwriteCurvature: could not open

lh./...

and

 mris_inflate -n 10 -sulc /...

resulting in error: MRISwriteCurvature: could not open /...
Lastly, I followed the response from Douglas N. Greve to try the new mkheadsurf.  When I tried that, the subjdir error went away, but the output paths errors with the mris_smooth and mris_inflate persisted.  The end result output files that I need were created, however, so I can go on with my work.

But I thought I'd reply to the list and let you know that I'm also getting these path errors.

Thanks for any help,
Megan
