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:

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.

Hi rick,

Since you mentioned multi-band scanning, I assume you refer to the MGH Simultaneous Multi-Slice sequence. In our case, each volume has 69 slices, with a SMS factor of 3 (e.g., 3 bands). TR=1500ms. I use Dicominfo in Matlab to read the slice timing information (see below) from the DICOM file, and assign such timing information to slices using to3d with a customized txt file given to tpattern option. And then do slice timing correction later using 3dTshift. Does this sound a reasonable way for multi-band scanning? Thanks!

Qiuhai
