PetSurfer: Other quantification algorithms?
by Elijah Mak 25 Jan '18

25 Jan '18

Dear Doug, In addition to the MRTM approaches, I was wondering if you have any plans to implement other algorithms in PetSurfer, such as supervised cluster analysis for extracting reference tissue activity? I am working with [11C]PK11195 PET data (neuroinflammation), for which there is no suitable reference region in neurodegenerative conditions. Hope to get your take on this please. Thanks very much. Best Wishes, Elijah

Tracula
by Nicole Mckay 25 Jan '18

25 Jan '18

Hi all, I have previously run full diffusion preprocessing using FSL and would like to now use tracula to construct the paths. Is it possible to input my already processed data into the tracula pipeline for just the path reconstruction and stats steps? I have already run recon-all too. Or perhaps is there a way I can insert my own corrected images into the prep step if it is running extra steps. My main reason for not wanting to start again from scratch is timing (I have 100 participants), but also that my preprocessing steps are slightly different. I use Eddy instead of Eddy_correct, and some of my participants needed individualised values for BET to work correctly. Any advice would be great, Nicole
