[FieldTrip] Question about Memory requirement Of Head model

[Julian Keil]

Dear Jing Wang,

this might be due to you using a 32bit System.
As far as I know, 32bit Windows can only use ~3 GB of Memory. At least that's what I experienced using Win XP, maybe it's different for the server.
However, I'd advise you to switch to a 64bit System and try again.

Best,

Julian
