Hi Adnan, I have run into those kinds of errors, and it can be very puzzling/frustrating.
A couple of common triggers: * If you have a non-english character set installed on your computer/login, then this can sometimes cause read/write issues. Removing the non-english character set sometimes makes the mapper happy (if not the user). * A more subtle one is that if I have previously mapped a paint volume, and have the algorithm set to paint enclosing voxel, then I can have trouble mapping a metric volume later -- until I change the mapping algorithm to one of the other (non-paint) options. The error message doesn't give you any hint that this is the problem, but I have seen metric errors like the one you report resolve under such circumstances. Another thing worth trying, when the mapper is being a pain, is to see if the problem persists with the command line version: caret_command -volume-map-to-surface caret_command -volume-map-to-surface-pals caret_command -volume-map-to-surface-roi-file Let us know if any of these helps.
