I'd need help for organizing my database.
I have 2 groups: children and adult.
I don't have individual MRI, so I have to use two templates: 1 for adults (from brainstorm) and one for children.
For each subject I have 6 conditions (pca1, pca2, pca 3, pca4, pca5, pca6).
In each condition I have 3 1-sec recordings.
I am going to make a source analysis.
I want to average the source of the 3 1-sec recordings for each subject.
Than I want to: 1) look at the average signal for each condition in each group and 2) compare each condition between groups (adult vs children).
I'm scripting each step.
I created a loop for importing the EEG recordings.
0. For the statistical analysis, would it be better to have the database organized as: patients> conditions> recordings or
conditions> patients> recordings? or
does it not matter at all?
- do you have a template for children? if yes of which age range?
otherwise I grabbed one adequate to my age range (7.5 to 13 yo) from an open source template database for children.
However this template has no fiducials or segmentation.
- I created a protocol selecting the option 'yes, use default anatomy'. But I have 2 default anatomies, 1 for children and 1 for adults. is there a way to avoid to import and segment the children anatomy for each subject? and to avoid also to repeat the issue of fiducials for each subject?
I know it's a bit chaotic, I hope it is understandable..
Thanks much for your time,
