Hi yvg,

It is most likely a memory error problem. You will need to allocate more RAM to your calls. You probably need at least 32GB or RAM for such big images (might be even more).

You can process the FLAIR images with mri_robust_template since they are slighly smaller than your T1 images.

Dear Samseg developers,

I have very high resolution T1 (512 x 512 x 240; voxel size: 0.469 x 0.469 x 1) and FLAIR images ( 384 x 384 x 128; voxel size: 0.495 x 0.495 x 1) and I would like to process them with the longitudinal processing of samseg but I have encountered different issues:

1.- mri_robust_template with T1 images: the process is killed after the following steps:

Registration::findSaturation - computing centroids - computing initial transform -- using translation info - Get Gaussian Pyramid Limits ( min size: 16 max size: -1 ) - Build Gaussian Pyramid ( Limits min steps: 0 max steps: 4 ) - Build Gaussian Pyramid ( Limits min steps: 0 max steps: 4 )

./samseg_mutua.sh: line 20: 1511261 Killed mri_robust_template ...

2.- mri_robust_template with FLAIR images can be processed without errors, but when I execute run_samseg_long to the FLAIR images, the process is killed without further explanations after the following command:

"Transforming points[0.49479165 0.49479164 0.49479165]".

Could you please please help me?

Best, yvg
