are your data really .46 mm in plane? It looks you are running out of memory, but even if you weren't it's very hard to reconstruct data that is that anisotropic (0.4688, 0.4688, 1.19996). You are better off getting 1mm isotropic and using it, which these days with 3T and 32 channels is only 4-6 min of imaging time.

Dear FS expert?

Today i put two contrast in the file {subjects},and run the command line "recon-all -s mgz -all", several minutes later,the terminal tells error,it says:
