Network matrix values different
Dear PANDA team ,
I used PANDA toolbox to compute the probabilistic tractography network matrix using AAL (116 ROIs) atlas, and I used the FSL independently to get the same matrix and somehow the values in the network matrix for both are quiet different. The matrix obtained from PANDA has almost 10 times higher values than I get when I do it only using FSL.So, I was wondering if PANDA is overestimating something or I am making some silly mistake in my processing in FSL ?
This is the processing I did in FSL.
1. run eddy current then bet
2. DTIfit
3. Bedpostx
4. Probtrackx2 command with --network option and --onewaycondition and steplength 0.5, 5000 streamlines
5. The obtained fdt_network matrix is then divided with waytotal matrix rowwise to obtain the final matrix.
Best,
Nabin
