Hi Irwin,
It sounds like the snapshots from tksurfer are fine, but the ones from
tkmedit are not being generated properly. It may be this peculiar bug
where ImageMagick has trouble reading rgb files. Try converting an rgb
file to a jpg 'convert file.rgb file.jpg'. You may get the error
'Improper image header'. The tksurfer tcl script saves tiff files, the
tkmedit tcl script saves rgbs, which may explain why some images are fine.

Hi-
I’ve come across a peculiar behavior with recon_checker, and am hoping
someone can shed some light on this.
I have used it 100’s of times in the past, but not for about 2 months. I
recently processed a large set of cases I wanted to QC. When I ran it, some,
but not all, of the snaps were corrupted. Specifically the talairach, aseg,
surfs, and all the ‘detailed snaps’, which are basically additional
instances of the aforementioned types. The inflated, curv, and parc are all
just fine. As the process runs, all images are being displayed in the pop-up
windows, and the html page is created.
While there have been no system changes which should affect this, I upgraded
from ImageMagick 6.5.4 to 6.8.1 to see if this would fix the problem. The
problem remains. And the problem remains w/ or w/o the flag for detailed
snaps.
If all of the images were corrupted, I would have certainly concluded
something has gone awry with my system. The fact that only some of the
images are corrupted makes me scratch my head.
Thoughts? Suggestions?
Thanks,
Wil
