hello all

I am currently running AlphaSim on one of my old datasets and I see different results for exactly the same command line that I used before. I had run a 3dFWHM on time series data and then used those values in AlphaSim.

the following is my command line:
3dFWHM -dset ts.reg.despike.obs.blur.fwhm.6.012+orig.\[0] -mask auto.mask.di3.obs.012+orig.

AlphaSim -nx 64 -ny 64 -nz 29 -dx 3.75 -dy 3.75 -dz 5.00 -iter 1000 -rmm 5.2 -pthr 9e-06 -fwhmx 23.11 -fwhmy 27.63 -fwhmz 20.58 -mask auto.mask.di3.obs.012+orig. -out Significant9e-06rad5.2.with.fwhm.and.mask


I had saved the previous output text file and so I could compare. Previously, I got a cluster size of 2 voxels for an alpha of 0.05. When I ran the same command line today, I dont even get a 0.05 in the alpha. It starts with a 0.02. I also ran it again as well as changed the number of iterations to 4000 and ran it again. This time it started with a 0.0225.

Is anyone else facing the same problem????

the AFNI version I am using is AFNI version=AFNI_2005_10_31_1510 [32-bit]


thanks
