Hello,

I have been running recon-all and trac-all analyses through remote access on the openmind.mit.edu cluster (from a windows7 i7 laptop using MobaXterm). The following software was set available:

module add openmind/fsl/5.0.7

module add openmind/freesurfer/5.3.0

module add openmind/git

module add netcdf/gcc/64/4.3.1.1

module add cuda55/toolkit/5.5.22

export LD_LIBRARY_PATH=/om/user/satra/projects/SAD/scripts/lib/:$LD_LIBRARY_PATH

export LD_LIBRARY_PATH=/om/user/ksitek/HCP/scripts/lib/:/cm/shared/apps/cuda55/toolkit/5.5.22/lib64:/cm/shared/apps/cuda55/toolkit/5.5.22/lib:/cm/shared/apps/cuda65/toolkit/6.5.14/lib64:$LD_LIBRARY_PATH

I guess all analyses went fine, but when I try to inspect output data by using freeview I encounter the following problem: I can open Freeview but when it tries to open a brain volume, the software always crashes and gives this error message:

boets_env[20:08][2.53][26%]bboets@openmind:dmri$ freeview -v dtifit_FA.nii.gz & [1] 7594 boets_env[20:09][2.58][26%]bboets@openmind:dmri$ X Error: BadRequest (invalid request code or no such operation) 1 Extension: 146 (Uknown extension) Minor opcode: 187 (Unknown request) Resource id: 0x8000c3 [xcb] Too much data requested from _XRead [xcb] This is most likely caused by a broken X extension library [xcb] Aborting, sorry about that. freeview.bin: xcb_io.c:735: _XRead: Assertion `!xcb_xlib_too_much_data_requested' failed. Abort freeview -v dtifit_FA.nii.gz [1]+ Exit 134 freeview -v dtifit_FA.nii.gz

I logged in into the server using ssh. The problem is identical while using ssh –X or ssh –Y.

(likewise if I try to visualize images through mricron on the server it works extremely slowly and unreliably ...)

Do you have any advice on how to handle this? I did not find any solutions in the archive?

Thanks!

Bart
