Writing tck file from vistasoft....

[htakemur]

Hello,

When I tried to see .tck file exported from vistasoft in MRView, I got a following error:

I guess that perhaps some information on .tck export may not have some header information required in MRView. If any of you had a similar experience, I would like to discuss how to move forward.

I can't think of why this is happening, can you run "head track.tck" to show what's at the top of your .tck? You should see something like

mrtrix tracks
act: 5tt.mif
backtrack: variable
crop_at_gmwmi: 1
downsample_factor: 3
fod_power: 0.25
init_threshold: 0.0500000007
lmax: variable
max_angle: variable
max_num_seeds: 15000000
...

By the way, I am attending some personal business. I might not be able to respond until later next week.

I think that you contributed some function for exporting fg file to .tck format.

I guess that perhaps some information on .tck export may not have some header information required in MRView. Do you have any thoughts on this, or have you ever seen similar error?

I will have a look at header informations, and try to compare those of tck files which work and do not work with mrView. I appreciate your response; I will try to handle it by myself at this moment.

I think that I figured out the issue --- please see my pull request. I will close this issue.
