I am uploading a CFF to TVB and for the Key_edge_weight, I want to multiply 2 of the attributes in the CFF file together: FA*number of fibers. Is there a way I can input the data so that the multiplication happens inside the TVB, or do I need to manipulate the CFF file prior to uploading?
Currently there is no support for the multiplication to happen in TVB.
You will need to do it outside.
In case this is something that you foresee to be needed often, we can create a feature request and add the feature in TVB in the next weeks.
That would be a useful feature, since we currently have connectomes with several attributes and aren't sure yet which attributes we will end up multiplying together to use as weights, so it would be nice to be able to test several different combinations (FA and RD multiplied by number of fibers).
