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 pt,
ah, I didn't know about FAT_MVM_DEMO but yes that is also suitable.

Oddly, while fat_mvm_prep.py completed for me, not all the roi connections were extracted into _MVMtbl.txt. As I have 318 rois, there should be 318x318 connections including AND and OR-logic. However, only 34 [seemingly random] roi connections were extracted:
048__159
058__104
070__071
070__089
070__157
074__159
079__089
079__157
079__158
089__091
089__157
091__093
143__144
143__145
144__145
156__159
157__158
157__159
172__188
222__304
229__230
229__248
229__316
230__248
238__248
238__252
241__244
248__250
248__316
276__279
303__304
316__317
316__318
317__318

Any idea why? (I just emailed you the text data so you can see what I'm working with!)

I'm also trying to make sure I understand whether to use -u / -- unionize option. My understanding is that any '0' values in the FA matrix means that there were no tracts found, thus '0' is actually equivalent to 'NA', correct? In that case, I believe I should not use -u because I do not want to place a value of '0' for nonexistent tracts.

PS: If you end up believing that fat_mat_tableize.py should be usable with my data let me know, because it does seem more streamlined. I do not plan to use 3dMVM as I'll be exporting everything to R.
