Hi, all
Sorry for sending several identical emails, as I repeatedly got replies saying
my emails are waiting to be approved.
So, basically I have four ROIs: PFC_L.border, ATC_L.border; IPL_L.border and
OC_L.border. I want to parcellate PFC_L, according to the connectivity inputs
from the other three ROIs. So, I run 'probtrackx2', with PFC_L as the seed and
other three as the targets. As all files are surface files, after the run, I
get several files like below: seeds_to_ATC.gii.ascseeds_to_IPL.gii.asc...
However, I find that workbench cannot read these standard ASCII files. So my
question is how I can read these surface files from FSL in workbench?
I kind of figured out a workaround after I posted the question: it seems that a
file called "matrix_seeds_to_all_targets" contains N*P matrix, with N being the
number of vertex in the seed mask and P being the number of target masks. The
values seem to be the number of connected streamlines. So, I may write a simple
matlab script to parcellate the seed mask myself by using "winner-take-all"
strategy, based on the matrix and their corersponding vertex on the surface.
If you know any better ways, please let me know.
Many thanksLongchuan

Hi Longchuan,
Can you give some details on what the seeds and targets are?
Peace,

Subject: [HCP-Users] Visualize outputs of seeds to targets classification in
workbench
Hi, HCP experts
I searched this topic in the mailing list for a while and seem not have found
the answer: after I performed seed-to-target analyses in probtrackx2 using
surface-based ROIs, how can I convert the results "seed_to_target_ROIs.asc" to
a format that is supported by Workbench and could be loaded and visualized in
WB?
Thank you in advance!Longchuan
