Compute head model issue

Bugs
1

I am trying to compute a head model and I keep getting this error:

OpenMEEG error #1:
./om_assemble: /usr/lib64/libz.so.1: no version information available (required by /path/.brainstorm/openmeeg/linux64/libOpenMEEGMaths.so.1)
./om_assemble: /lib64/libc.so.6: version ‘GLIBC_2.7’ not found (required by /path/.brainstorm/openmeeg/linux64/libOpenMEEGMaths.so.1)

Is this an issue where I need to update Brainstorm to the newest version?

Thanks

hi maggie,

can you tell me when this commands says:

gcc --version

also what linux system/version are you running?

I suspect you have an old system… or maybe too new…

Hi Alex

gcc (GCC) 4.1.2 20080704 (Red Hat 4.1.2-44)

RedHat 2.6.18-128.el5

can you try with these binaries:

http://openmeeg.gforge.inria.fr/download/OpenMEEG-2.1.dev-Linux.amd64-gcc-4.1.2-static.tar.gz

or

http://openmeeg.gforge.inria.fr/download/OpenMEEG-2.1.dev-Linux.amd64-gcc-4.1.2-OpenMP-static.tar.gz

that should support parallel processing.

let me know how it goes

Maggie: To replace the binaries:

  • delete what is in $HOME/.brainstorm/openmeeg/linux64
  • tar zxvf OpenMEEG…tar.gz
  • move the contents of the subfolders “bin” and “lib” directly into $HOME/.brainstorm/openmeeg/linux64
  • then run again the forward model computation from Brainstorm

Alex: Do I need to update the default downloaded packages?

no don’t. It’s an old version of GCC.

Hi Francois and Alex,

I followed those instructions, but am still getting the same error when trying to run the head model.

Hi Francois,

The second set of binaries that you sent did the trick. OpenMEEG BEM now runs. We’re getting a new error now about the mesh not being closed, but this is probably an issue with the MR.

Thanks for your help,
Maggie.

Hi Maggie,

Indeed, it looks like OpenMEEG has now all the libraries it needs to run.
Now you have to generate carefully your surfaces to make sure they are compatible with OpenMEEG.

You can read the corresponding tutorial:
http://neuroimage.usc.edu/brainstorm/Tutorials/TutBem
Or search the forum for “OpenMEEG” for solutions for common errors. For example:

If you don’t find your answer there, please post the full error message you’re getting on the forum.
