Dear Ged,
Nifti was introduced precisely in order to get rid of these
inconsistencies
in format, like the scaling in the Analyze format. As all the major
software packages, including FSL and SPM, are moving away from
Analyze support, this is no longer going to be an issue in the future.
I would strongly encourage you to avoid Analyze format if possible.
It is likely to support for the Analyze format will be dropped in the
future.
|f you really need to extract this information from the SPM Analyze
files you can script it yourself by looking at the funused1 and funused2
fields in the avwhd output. By using these with avwmaths it is easy
enough to rescale appropriately.
All the best,
Mark
