Hello SPMist
I am looking for some information about the header files structure.
Could anybody tell me about the scale and the origin position and
description in the header files since the analyse format description
avalable at the Analyse site doesn't mention it
(http://turboguide.com/data2/cdprod1/doc/software.frame/001/160.pub.Mayo.Fou
ndation.html).
The most puzzeling factor for me is the scale factor, but reading the
mails, it seems that it is only concerning PET data. How and where should
it be set in the header ?
Looking to the header files of the avalable data at the SPM site, there is
some fixed values not described : the first short int unused in the image
dimention structure is often fixed to 28013, and the 2nd unused float of
the same structure is often fixed to 0.125. Could anybody tell me more
about those value ?
Thanks for answering.
