Dear Sir/Madam,

I have been using SIMNIBS headreco segmentation to generate cortical surface reconstruction for stroke patients, knowing CAT12 is not optimized for these types of brains.

The newest version of CAT12 includes a function (Stroke Lesion Correction), which produces a better segmentation result after my inspection. Is there a way to incorporate these segmentation results directly, to proceed to the next stage?

 I tried to use the segmentation results from that, to replace the results in /segments/cat directories, and binarized the segmentation mask. However, when I run the preparecat function, I encounter the following errors.

I suspect that the error results from the difference of the number of vertices of the mesh generated from the initial preparevol command and the custom segmentation results from new CAT12.
Is there any way to generate a .off file based on the new CAT12 features?

I have been using Simnibs for a long time and really appreciate your team's effort in maintaining and updating the software for better progression of this research field. Look forward to your reply

Best regards,
