Anda, How much RAM and swap space do you have? This is crashing at a point when more memory is being grabbed. We recommend RAM of 512MB or more, and swap space at least equal to RAM (although 2GB min recommended). Failing that, what platform are you on? Cheers, Mark. Mark Woolrich.

Everything is checked in terms of: correct data files (design is with 3-column format) and nr. of EVs and the design in these subjects is accepted without any problem. Something goes wrong after the "smoothing" and i get this message that differs from the other log reports starting with "Signal 6": > > rm -rf stats/postSmoothVol* stats/preSmoothVol* stats/usanSize* > Completed > Tukey M = 24 > Tukey estimates...
