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 there,

I was performing 3dMatch, but wanted to look at the folder that is outputted which reports the percentage match between the standard functional template (brain networks) against your data (independent components)

The REF folder looked something like this:

0 5 0.504 0.187
1 8 0.460 0.200
2 3 0.397 0.164
3 4 0.390 0.141
4 17 0.428 0.107
5 10 0.404 0.182
6 0 0.512 0.266

the first column lists all the 7 networks, The second column contains the Indpendent components from MELODIC (GICA) that matched the most with each of the 7 networks. And the column next to that is the percentage match.

But I was wondering.. would it look bad to report a match percentage less than 50%? Or should we argue that, that's what the data is like and that it's beyond our control?

For instance, the DMN doesn't strictly have DMN regions activated but it also contains the occipital, and other components, therefore making it only match 51% (network 6)

I'm not sure what to do. Or is this okay?
