ParticipantDear Hivemind,
I am using Brainsuite to analyze the fibertracks of 107 subjects.
Is there a way to automate the saving of multiple fibertracks for each subject?Example:
I have 36 ROI´s (e.g. Putamen to Thalamus, etc.) that I wanna save with Brainsuite.
Is there a way to “give” Brainsuite a list to save all selected ROI´s?At the moment it is very time intensive to click through the whole process to save so many ROI´s for so many subjects, if there is any way to make it faster, I´d really appreciate your input!

KeymasterHello –
I have written some command-line tools that can probably do this. I thought we were distributing them, but I just checked and they aren’t in the public release yet.
Can you be more specific about what you are trying to do and what steps you are taking? Are you trying to give it pairs of ROIs and save out a .dft file?
thanks,
David -

ParticipantHi David,
thanks for the quick reply!I am trying to single out selected fiber tracks and save them for further FA and MD calculations with TractConnect, but on a larger scale.
At the moment I am manually selecting the desired fibertracks using the computed tracks from the connectivity matrix, and then saving the filtered fiber tracks (e.g. L. Insula to L. Amygdala) as a BrainSuite Track File (*dft).
What I am looking for now is a way to not click through this process manually for each of my predefined fiber tracks. -

KeymasterIf you send an email to support at brainsuite.org, I’ll see what I can do. Let me know what platform (Mac/Win/Linux) you are using.
thanks,

Keymasterhi Adrien –
I’m working on it — still need to do some testing. Will follow up by email soon with a few questions.

KeymasterHi Adrien –
It took a little longer than expected because we have been preparing a major release of BrainSuite (v23a, out now), as well as an updated BrainSuite BIDS App. We were making some improvements to the underlying methods, including some optimizations in how the streamline filtering is performed.
The new package includes a program call filterdft, which is in the bin directory. You can use it to perform all of the filtering options that are available in the GUI. These are performed (in order, but the order shouldn’t matter):
* remove streamlines shorter than the length threshold if specified (-l setting)
* remove streamlines that intersect labels in the exclude list (specified as –exclude # # #)
* remove streamlines based on spherical ROI filters if specified (uses an xml file)
* remove streamlines unless they intersect labels in the include list (specified as –include # # #)By default, it will use an or operation for the final check, so if you wanted to include all streamlines that intersect the superior frontal gyri, you would run:
filterdft -i input.dft -o output.dft --include 120 121
You can use the –and flag if you want to have the streamlines go through *all* labels specified, e.g,. if you want to find streamlines that connect the brainstem (800) and cerebellum (900), you would use:
filterdft -i input.dft -o output.dft --include 800 900 --and
The full set of options is listed below.
Let me know if that provides the functionality that you need.
thanks,

ParticipantHi David,
Thank you for your work!
I used the following command which only worked once i executed it as an administrator:
C:\Program Files\BrainSuite23a\bin> filterdft -i ‘C:\files\AllTracksVP001.dft’ -o test.dft -l ‘C:\files\T1.svreg.init.label.nii.gz’ –include 131 225 –andBut the output file was an empty .dft file.
My question now is if I used a wrong label or input file?
Kind regards,
Adrien -

ParticipantWe worked it out, there was a problem with the used label!
Thank you very much again for this addition, works like a charm now!
Kind regards,
Adrien
