[Camino-users] pico

[Silvia De Santis]

Hello,

I am trying to use pico to estimate the probability of connectivity between a bunch of voxels and I get inconsistent results, so I was seeking for help to understand what I am doing wrong. 

cat brainDT.Bdouble | picopdfs -inputmodel dt -luts picoTable.dat > brainPICoPDFs.Bdouble

track -inputfile brainPICoPDFs.Bdouble -inputmodel pico -seedfile mask | procstreamlines -outputcp -outputroot results/ -seedfile mask  
 
> brainDT.Bdouble is obtained with dtfit and looks ok
> mask is an indexed mask of voxels (from 1 to n_voxels)
> picoTable is obtained with dtlutgen

I get .img files that basically contains white spots that are outside the brain, and since this is the first time I use camino I am really clueless.

Any kind of help would be greatly appreciated!

Silvia
