Hi. I just want to make sure my understanding of how 3dDeconvolve works concerning disk access is correct.
Assuming a system has enough free memory to store all of the necessary data, is the hard drive accessed at all during a Deconvolution? I was under the impression that all of the data was loaded into memory at the beginning of execution and only written back to the disk when the job was finished.

Thanks,
Emmette
