Hi Doug, I am using w files to show ECoG activation at localized regions on the cortex. So preferably, I would like to show temporal dynamics too (thus the multi-frame question, and thanks for pointing me to MNE). What will replace w files going forward? i think w file's file format is very conci

2013-06-27 Thread Zhongtian Dai
Hi, I want to ask some questions about w files: 1. does Freeview read and display w files? (if not, any plan to support it?) 2. does tksurfer support custom color scale? how to change a color scale's bounds? they seem to change with overlay's min and max but not consistently. 3. does anything rese

[Freesurfer] Memory Consumption of GPU-assisted Freesurfer?

2013-02-04 Thread Zhongtian Dai
Hi, I wonder how much graphic card memory is needed by the CUDA commands. We have two Quadro NVS 295's with 256MB memory and the CUDA commands all report "out of memory" errors. I know the cards are kind of outdated but I want to make sure a new card would meet the task before purchasing. A separ
