Hello,

I have been unable to load one subject's surface, for purposes of viewing a functional mask on the surface. I noticed this warning in the text output: "surfer: WARNING: fov was ~0, setting to 0.256". The warning, and subsequent failure to load the surface, occurred when I called surf-sess using the same parameters I had used successfully to load all other subjects' mask data. The surface did not load, and instead a red rectangle and a blue rectangle were rendered. The warning I mentioned was the only suspicious line in the text output from surf-sess. The other output (including the "can't find tal...") was present for the subjects where the command was successful, not just for this subject.

Here is the command I used (accessing a list of subjects, one of which was the one that did not load):

surf-sess -sf Subject_Lists/bw-group-error-5 -analysis EMerror -contrast dACC_rh_pos_0_ASce68 -map mask -hemi rh -fthresh .5

Here is the context of the warning:

can't find talairach file '/space/ventzl/1/users/SUBJECTS_DIR/mano011/mri/T1/COR-.info/../transforms/talairach.xfm'
surfer: Reading header info from /space/ventzl/1/users/SUBJECTS_DIR/mano011/mri/T1/COR-.info

surfer: WARNING: fov was ~0, setting to 0.256

surfer: vertices=95942, faces=192364
can't find talairach file '/space/ventzl/1/users/SUBJECTS_DIR/mano011/surf/../mri/orig/COR-.info/../transforms/talairach.xfm'
surfer: ### redraw failed: no gl window open

Do you know what might cause a problem like this? Thanks in advance for any help or advice,

Rob
