Hi,
I tried to convert some dicom images (Philips, Intera 3T) into mnc format using dcm2mnc and I got the following error:
Checking file types...

Hi Andrew,

Yes, that is correct.

Yes, by setting PATH=/usr/local/mni/bin:$PATH the initial problem with mritotal was fixed.
Now, I can still not run mritotal due to make_model. I was not able to build the model during make install process in mni_autoreg_model-1.03 directory.
If I run ./mritotal in.mnc out.xfm I would get the following error:
Loading configuration file /usr/local/mni/bin/../etc/mni_autoreg/mritotal.cfg
Loading protocol default (protocol file = /usr/local/mni/bin/../etc/mni_autoreg/mritotal.default.cfg)
/usr/local/mni/bin/../share/mni_autoreg/average_305_16_blur.mnc does not exist
/usr/local/mni/bin/../share/mni_autoreg/average_305_8_blur.mnc does not exist

/usr/local/mni/bin/../share/mni_autoreg/average_305_8_mask.mnc does not exist
In /usr/local/mni/share/mni_autoreg there are only 3 files:
average_305_headmask.mnc
average_305_mask.mnc
average_305.mnc.
Thank you for your help.
Teo

Hello everyone,
I have a few questions regarding the MNI Autoreg.
1. Does anyone know where I can find the latest version of MNI Autoreg? Is the one on http://www.bic.mni.mcgill.ca/software/distribution/ the latest version?
2. Is this version based on optical flow or intensity-based cross correlation? I want to use intensity-based corss correlation. Where can I find that?
3. If I change the target image from mni_305.mnc to sbrain.mnc, will that significantly affect the registration accuracy?
Thanks a lot!
Jessie

Intensity cross correlation by default.

sbrain? I'm afraid you lost me.. :)

What was the error in the install process? Looks to me (from the
below) that the install didn't complete and only files were copied. i
suspect again this is because make_model (part of the mni_autoreg
install) was not on your path when you installed the model files
package.

So, now that you have fixed your path you can either re-install the
model files or do this:
cd /usr/loca/mni/share/mni_autoreg
make_model average_305

It is the notion of preserving signal as it relates to area in the
original image. ie: if you shrink an area by 10% you increase its
signal by 10%. Thus if you integrate across an area both before and
after resampling you will get the same result. Sometimes you want to
do this and sometimes you dont.....

no
> Maybe, it would be better to decompose the vectors at each voxel of the deformation and resample that instead. The only problem is to reassemble the vector field.
why? This is in effect what mincresample does.
