Hi Gina,

In general I think that you really should provide a bit more information. I at least don’t remember what your problem is all about, and if you would like people to think along (who by the way all do this on a voluntary basis), you should really give us something to work on, and present things on a silver platter, rather than expecting us to dig through our (no doubt extensive) e-mail archives, which moreover relies on the assumption that we still have your earlier e-mails handy.
This being said, I dug through my archive, and saw that I already replied to an e-mail of yours that has the same subject header.

Here’s my earlier reply:

Hi Gina,

A dimensionality of 92232 ( ^ 2) suggests that you have 28 times the number of inside dipoles. I suspect a interaction between FieldTrip’s internal data bookkeeping and perhaps your specification of the input data/cfg.

Where does this factor of 28 come from?


As you can see, this reply contained a question, which as far as I am concerned has not been answered. In other words, the ball is in your court.
