Had this error after while trying to register.
could not launch Label Left Hemisphere Surface please check that the executable /Applications/BrainSuite18a/svreg/bin/svreg_label_surf_hemi.sh exists and that /Users/walidyassine/Documents/Todai/Studies/VoiceTask_study/BS_SPGR/A02 is a valid directory.
I checked both, and both are fine!
Any advice what to do next?

Hi Wy, I will try to help you with this.
Can you try running /Applications/BrainSuite18a/svreg/bin/svreg_label_surf_hemi.sh
from the command line and let me know what message you get?

Thank you very much.
Here is the output.
surface registration and labeling (svreg)
This is the main program for surface registration. First, the surface is
smoothed to create a multiresolution representation of the surface. An
initial registration is performed by aligning the 3D coordinates of this
smoothed surface. This is followed by p-harmonic mapping to a square and

Here is one of the errors i am getting from the run..

A matrix with a negative or zero determinant was encountered. (AIR_NON_POSITIVE_DETERMINANT_ERROR)

another is the pial line. While brainsuite is running, i can see that it was too much inside the brain, sometimes including the inner temporal!!!

Ok thanks. From the BrainSuite GUI, goto Cortex->Select SVReg directory.
Then from the dialog box, goto BrainSuite installation folder and select directory named svreg.
After this, try running the whole sequence for your subject data and it should work.
The next error is something else. It is due to some errors in surface extraction. Please make sure that the cortical surface you get look reasonable, as shown on brainsuite website.

I am also getting the same error
Registration Process Error
could not launch Label Left Hemisphere Surface
please check that the executable /home/alphin/Downloads/BrainSuite19a/svreg/bin/svreg_label_surf_hemi.sh exists and that /home/alphin/Downloads is a valid directory.
Please see log window for process output
I selected the SVReg directory and still facing the same issue.

Does the /home/alphin/Downloads/BrainSuite19a/svreg/bin/svreg_label_surf_hemi.sh
file exist on your computer?
