    Thank you very much Andy for your quick response.

    Is there any way to calculate the VTA in native space? Or transform the vat_right.nii to native space?

    Kind regards,
    Maria

    Thank you for your reply Ningfei.

    I am not really sure they are that similar, but I wanted to see if it was able to detect the SEEG electrodes anyway. I have not been able to detect the SEEG electrodes in the Manual method, since it is quite hard to keep track with the 12 electrodes and try to select different ones each time… I am not sure if there is any work around that but it would be really helpful.

    Cheers,

    Hi Ningfei,

    Thank you for your fast response! The electrodes implanted for SEEG are ADTECH, and I was trying to use the SDE-08 S8 electrode model, for 12 electrodes. I read that it should be relatively simple to generate a new model, however I am not sure how to do that. Do you know where I could find some information about that?

    We were hoping to do the detection automatically, but for now I will try to do it with the Manua method :)

    Thank you,

    Maria

    Hello Ningfei,

    Thank you for your suggestion. Changing to the options you gave me doesn´t givean error, and it is able to reconstruct them, however when I have to localize them I have to move a lot the electrodes for them to match the images. They are located in the thalamus so I am not sure if that could be the reason why it doesn´t detect them as easily.

    I have another question regarding the same topic. I am trying to do the same with SEEG electrodes, and although it doesn´t give any errors, when I have to localize them, it seems like I can not see correctly any of the artifacts and I am unable to find them. I know the toolbox is not specialized in SEEG electrodes, but I was wondering if it could be due to the reconstruction not being optimal due to not having the correct electrode model, (which could I generate myself somehow?)

    Thank you again,

    Maria

    Hi Ningfei!

    Thank you so much for the quick reply. I have tried PaCER, TRAC/CORE, and Refined TRAC/CORE with different mask window size, from 5 to 15, but none of them work. I have only been able to localize them manually.

    Is there anything else I could check to see why I can only do it manually? Is there any requirement regarding the images or the electrode positioning?

    Thank you,

    Maria
