Hello,
I used wget to get all the updated afni files (and I'm sure I using these now), but I'm not getting it to work yet.

I have 37 mosaic images, where each mosaic image contains 40 (7x7 layout) slices at one time--(there are 37 moments in time).

I use:

to3d -prefix gst_new -time:zt 40 37 2s alt+z lee_roth+1_+20021121+135947+00009*

and get:

*** Number of slices on command line = 37
*** Number of slices needed for -time: = 1480
*** Something is wrong with your command line!

this seems as though to3d wants single images rather than mosaics.
Just to be clear, these are dicom files from a Siemens Allegra scanner. They come in the format like 1.2.840.113619.2.1.6637.3053478798.3.27.920368684, not .ima. I'm not clear as whether these are different formats.

any words about this or my problem?

George
