Hello again

Actually this is a part of a bigger script. It is an iterative process for every ROI of the brain. As of now I am using 3dmaskdump/3dmaskave, getting co-ordinates and then using 3dUndump to make a dataset. This dataset, rather single voxel then goes through another part of the script where it's corresponding time series is dumped and so on......

I tried using the -slow option and I get a mask dataset that covers my whole AFNI window. I actually need that tiny voxel isolated out so that it can proceed to the next time series dumping part of the script.

I also tried the method suggested by Vince and well it still cannot recognise the scaled value apart from the internal value and so I get my previous error.

Was just trying to avoid the extra 2/3 steps I was using in the script.

Thanks for all the suggestions
