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

Hi there,

I was trying to determine the maximum number of streams that run between each pair of ROI's.

Would be the right way to go about it:

1) Count the number of voxels from the source ROI (aka seed ROI)
2) Multiply the count by 5 (5 being the default number of seeds/voxel)

Or is this approach wrong?

The way I understand it is that the way Monte-Carlo works is by generating the 5 possible streams from the source ROI, that's why I would approach it in that manner.

Please let me know what your thoughts are :)
