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,

This might be a very silly question...

So I have two datasets: one with correlation coefficient r-values and other with beta-values. They are related by a scaling factor, so the significantly activated regions are very similar between these two datasets. Also, the range of t-statistics (min, max) are the same. But if look the maps the one with r-values are all yellow blobs (intensity bar from blue to yellow (top)) whereas the other datasets with beta-values show all red/orange blobs (two intervals down from yellow in the intensity bar). And I'm afraid I'm going to say that I don't understand why this is. Could anybody help me understand this?
