[Freesurfer] mris_pmake error

Hi,

when trying to use mris_pmake I get error messages: when I run:mris_pmake I get: sh: cannot create lock: Permission denied

mris_pmake I'm sorry, but an error condition has occurred. While I was checking on the options file, I couldn't access the options file. Does it exist?

Exiting to system with code 40

When I run: sudo ./bin/mris_pmake I get: mris_pmake I'm sorry, but an error condition has occurred. While I was processing environment, it seems that the SUBJECTS_DIR env variable is not set.

Exiting to system with code 10

I did specify SUBJECTS_DIR in SetUpFreesurfer.sh that I source in the bashrc file and the variable is set for the other freesurfer functions.

I am using freesurfer-Linux-centos4_x86_64-stable-pub-v5.1.0 on ubuntu 11.04.

Any help is much appreciated.

thanks,

Stephan
