Hi - one thing is that we estimate (z versions of) netmats separately for each 15min run and then average the 4 netmats to give a single netmat per subject. Cheers. On 30 Mar 2015, at 18:14, Yizhou Ma maxxx...@umn.edu wrote: Hi Timothy, Thank you for pointing that out. I typed that wrong

Hi Timothy, Thank you for pointing that out. I typed that wrong but I used the correct transformation in matlab. As I said my transformed z scores are actually almost perfectly linearly correlated with HCP netmats, though the latter is much larger. I want to understand why the latter is larger

[HCP-Users] netmats in HCP

2015-03-30 Thread Yizhou Ma
Dear HCP experts, I am trying to reproduce the individual netmats from HCP500-PTN so that I am sure where the numbers come from. I used individual node timeseries in /ts2/subjID and did correlation in matlab. I then used fisher's z transformation: .5*ln(1+r)-ln(1-r). The resulting netmat is
