Electrode localisation only

[Rey-94]

Hello, i have been trying to use yael to do electrode localisation. I cannot figure out a way to only do that. I already have all my MRI and CT preprocessed and aligned. Do i really need to start from scratch with a fresh subject to use the tool ? Can i just upload my files ? If yes can someone explain how to do that ? Thank you

Hi @Rey-94 , you can avoid all preprocessing by copying over your CT and MRI files into the RAVE directory. If you would like to schedule a zoom walk-through. Please send your edu email to help at rave.wiki.

Here are the steps to get around, assuming your subject code is BCI001, and the default RAVE raw data directory is under your home folder.

Step 1: create a subject result folder under ~/rave_data/data_dir/YAEL/BCI001

Step 2: create a subject raw folder under ~/rave_data/raw_dir/BCI001/rave-imaging, and copy your files to the folder (see screenshot below)

• coregistration folder contains the aligned CT and MRI reference
• fs is the FreeSurfer folder (if you have it already, copy the subject folder here and rename to fs)

Step 3: use rave::start_yael() command to open YAEL, and you should be able to start localization by choosing project YAEL, and subject code BCI2000.
