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

3dROIstats won't use masks that are stored as floating point numbers unless you use the -mask2fshort option also. Somewhere in your processing stream, your mask is stored as a floating point number which is fine except for this minor nuisance. So a 2 may be stored as 2.000. To see the type of data, use 3dinfo for the dataset. The "datum type" is listed for each sub-brick. Dataset types include byte, short and float (there are also complex and RGB too).

3dmerge and 3dcalc both use the -datum option to control output type. If you would like to force short integer type, use "-datum short" for those programs.
