(of note, the word “regressor” is wrong here, it has some historic reasons why I’m used to reference the variables entered into lead group as “regressors”). In this case, it’s basically just a variable that codes for the groups.
Hi Rubens,
maybe your regressor is set up incorrectly. It should be all ones for group 1 and all zeros for group 2.
So assume you have e.g. 5 top responders and 5 poor responders and want to run a paired t-test on their VTA intersections with the STN, then you would add a vector like
[1
1
1
1
1
0
0
0
0
0];
as the regressor. Then click on the group comparison button.And then it should work.

…maybe also check out this page for some general advice about how Lead-DBS is built:

Hi Maria,
yes, the export code.. button doesn’t help you there.
But you’re right that the ea_genvat_*.m files should work.
You can generate an options struct by usingoptions=ea_getptopts(‘/path/to/your/patient/’);

Hi Joey,
it seems like you can simply uncomment those lines (in general).
https://github.com/netstim/leaddbs/commit/51cdd3ba26ec1671d99b53657dcea6d2fa4f8d0cHope that fixes it!

Hi, you can use lead group for that.
Check out the walkthrough video on the website to get a brief introduction.Yes of course Tools -> map file from template to anchor space (then it will be in the space of anat_t1.nii).

Hi Maria,
vat_right.nii is the right VTA in MNI space.
vat_efield_right.nii is the right E-Field in MNI space.
vat_efield_gauss_right.nii is the same but “gaussianized” with the ea_normal.m function (see van Albada 2006).You don’t need the ea_stats.mat for anything outside of Lead-DBS.

Can ignore.
For future reference: https://musescore.org/de/handbook/developers-handbook/getting-started/how-write-good-bug-report-step-step-instructionsHi Kirk,
maybe this quickstart primer is helpful?
Regarding software, you only need Lead-DBS and SPM12 on your path (and nothing else).
But you defnitely need some experience with Matlab to have fun with Lead-DBS.Best, Andy
No, there is no GUI for that. Of course you could create spheres at their location and then run fibertracking e.g. using FSL or similar.
Hint: If you use the E-Field as seeds (instead of the VTA), it basically boils down to just using the coordinates. Change “binary” to “efield” in Preferences to do so.
