AFNI Message Board

Dear AFNI users-

We are very pleased to announce that the new AFNI Message Board framework is up! Please join us at:

https://discuss.afni.nimh.nih.gov

Existing user accounts have been migrated, so returning users can login by requesting a password reset. New users can create accounts, as well, through a standard account creation process. Please note that these setup emails might initially go to spam folders (esp. for NIH users!), so please check those locations in the beginning.

The current Message Board discussion threads have been migrated to the new framework. The current Message Board will remain visible, but read-only, for a little while.

Sincerely, AFNI HQ

Hello,

I hope this finds you in good spirits!

SUMA crashes when a labeled volume is stored as floats.

From a SUMA/ directory, running:
> suma -vol aparc.a2009s+aseg_rank.nii
Opens a blank viewer with the following warnings echoed in the shell:
Error SUMA_SetUniqueValsAttr (suma_datasets.c:1539):
Bad column type 6 for unique values
-- Error SUMA_CreateCmapForLabelDset (SUMA_Color.c:4139):
Either no unique values or too many of them:
0x0, 0 (256)
-- Error SUMA_CreateOverlayPointer (SUMA_Color.c:6372):
Failed to create new label dset cmap
-- Error SUMA_ColorizePlane (SUMA_Color.c:11471):
Where's your cmapname?
Opening the viewer controller causes SUMA to crash.

Copying the dataset to a short format along with the label tables get around the problem.
3dcalc -a aparc.a2009s+aseg_rank.nii -expr 'a' -prefix ttt.nii -datum short
3drefit -copytables aparc.a2009s+aseg.nii ttt.nii

Cheers,
ZXu
