I was trying to test some things in simulations apart from the work I am doing, and I decided to use the GUI and the default project in TVB. I intended to do some surface anatomy simulations, but when I went to introduce the region mapping, I saw that there were problems. I attach an image so that you can see it, when I click on the arrow to open the region mapping options, I see that it is empty. That is, I don't have any options to choose from. However, when I started using TVB, I remember doing surface simulations where I did use region mapping. Here is another image showing the option I had available. As the region mapping is a text file that has to be inserted in the zip file that is uploaded to the TVB platform, that is, it is not defined once you are using the graphical interface, I don't know where the problem is to find it again.
If there is someone who has had a similar problem and can give me some advice on how to get the region mapping available again, I would appreciate it.
Thank you in advanced.
