[MINC-users] inormalize-2.0.18: Volume and model dimensions do not match!

[Burt Crépeault]

Hi all,

I've recently built the latest MINC suite for OS X and am currently testing
everything. It appears that inormalize's behaviour has changed when using a
model file.

With version 2.0.09:

neon:install:# /opt/MEDICS/EX/etc/minc2/bin/inormalize -clobber -model
colin27.mnc 70.mnc 71.mnc

With version 2.0.18:

neon:install:# inormalize -clobber -model colin27.mnc 70.mnc 71.mnc
Reading volume

Selected normalization: medianOfRatios
Volume and model dimensions do not match!

What has changed since version 2.0.09? The changelog doesn't seem to contain
the answer. Is there a reason why we can no longer normalize images whose
dimensions differ from the model? Here are the dimensions for both:

neon:install:# mincinfo 70.mnc colin27.mnc
file: 70.mnc
image: unsigned short 0 to 65535
image dimensions: zspace yspace xspace
    dimension name         length         step        start
    --------------         ------         ----        -----
    zspace                    256      1.05469     -139.275
    yspace                    256      1.05469     -132.873
    xspace                    115          1.3     -79.0931


file: colin27.mnc
image: unsigned short 0 to 65535
image dimensions: zspace yspace xspace
    dimension name         length         step        start
    --------------         ------         ----        -----
    zspace                    181            1          -72
    yspace                    217            1         -126
    xspace                    181            1          -90

Thanks,

Burt.
