It sounds like an openGL rendering issue. If you run glxgears command, do you see a blank window or spinning 3D gears?

Hi Paul,

Thank you for your response. There was an issue with my description. I meant to refer to volume data. Freeview is displaying a black view, even though it loads the images. Unfortunately, nothing is visible.

Best,

Mahdi

Hi Mahdi,

I'm afraid I don't know what you mean by "Freeview opens fine but when I load a column in it just shows a black view."  What is a column in this context?

As for registration between PET and MR, have you seen this page?
MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://surfer.nmr.mgh.harvard.edu/fswiki/PetSurfer

It suggests using mri_coreg.

Dear FreeSurfer Team,

I'm currently a PhD student at Stevens Institute of Technology in New Jersey, USA, where my research focuses on MRI to PET translation. I have a number of problems. Freeview opens fine but when I load a column in it just shows a black view. Have you ever encountered this problem?
I'm so confused about using the tool for registration. Can I do registration between MRI and PET modalities of the same subject using "bbregister"?

Best,
Mahdi
