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

Dear colleagues,

I am trying to use the meica.py to process some multi-echo data, but I get some python errors in the program. I tried to process my own data and the demo data, but got the same error.

Here is the log output: 

++++++++++++++++++++++++

    none,ctb,betasv,v_T = fitmodels_direct(catd,v.T,eimum,t2s,tes,mmixN=vTmixN,full_sel=False)

    if mmixN == None: mmixN=mmix
ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()

I have read several posts about this value error but still can't find a way that really clearly explain how to fix the problem. I see why Python does not like what it's been written but I am not sure how to fix it. Does it have something to do with the numpy version? For the record, the numpy version I have is 1.13.1.

Thanks
Vincent
