Hello,

I am trying to run optseq2 but i am getting an error message.

Here is the command I use: optseq2 --ntp 160 --ev AL 4 16 --ev AR 4 16 --ev PL 4 16 --ev PR 4 16 --o AS --nkeep 12 --log ASfMRI --nsearch 10000 --psdwin 2 20 --tnullmin 2 --tnullmax 8 --tr 2 --sum ASfMRI-sum

here is the error message: INFO: Setting srand48() seed to 614559 optseq2 $Id: optseq2.c,v 2.12 2006/12/29 02:09:11 nicks Exp $ NoSearch = 0 nSearch = 10000 nKeep = 12 PctUpdate = 10.000000 nCB1Opt = 0 seed = 614559 Ntp = 160 TR = 2 TPreScan = 0 PSD Window = 2 20 2 nEvTypes = 4 EvNo Label Duration nRepsNom 1 AL 4.000 16 2 AR 4.000 16 3 PL 4.000 16 4 PR 4.000 16 PctVarEvReps = 0 VarEvRepsPerCond = 0 PolyOrder = -1 tNullMax = 8 tNullMin = 2 outstem = AS AR1 = 0 No refractory penalty Cost = eff OutStem = AS Summary File = ASfMRI-sum nTaskAvgs = 36 INFO: LogFile is ASfMRI outstem = AS *** glibc detected *** free(): invalid next size (normal): 0x00000000005af3e0 *** Abort

I have tried this on multiple machines and I have been getting the same type of error.

Thanks in advance for any help - Sheeva
