Dear All,  
I hope you are doing well.  
I am a PhD student and working on a project related to medical image segmentation. one of my tasks is to compare annotation/segmentation tools. To compare the tools, first I should open my raw binary files (.bin) originated from OCTA machine (1536h x2048w x 2044bscans) and then do anntation/segmentation on them.  
I have been able to do the task by Slicer but I have faced a problem in opening them by itk-snap. even by converting them into nrrd, I couldn’t show them. the nice part is here the 3d render of the image is generated and it is correct. but the image cannot be shown and all 3 planes are empty.

I would be grateful if you could help me.  
Best,  
Ali
