Open rachaelgarner opened 5 years ago
@rachaelgarner During the preprocess, RAVE
will automatically generate several "meta" files. electrodes.csv
is one of them. By default, all electrodes will be set to (0,0,0)
with a blank label. You can open this file, copy-paste MNI x
, y
, z
here directly to Coord_x
, Coord_y
, Coord_z
in electrodes.csv
. The column Label
is for the electrode name. Then RAVE
will render whatever coordinates given in this file.
Here's an example of electrodes.csv
.
To find this csv file, let's say your project is MyProj
and subject code is sub1
and data_dir
is using the default directory, then in ~/data_dir/MyProj/sub1/rave/meta/electrodes.csv
.
Hi, I'm working on registering the electrode contacts for a subject into a common space. Many of our subjects are using a 10/20 system, so I have each contact labeled as Cz, Fp1, etc. I found a study (Okamoto et al., 2004) that reported cartesian coordinates for this system in MNI space, and am wondering if these would be readable by RAVE? Also if so, where in my directory should I include a txt/csv file with the coordinates? From the demo data it looks like electrodes.csv is in data_dir, not raw dir, so would it be better to import the electrode coordinate file following preprocessing? Thanks!
