The GUI

Notes

The gui is a convenient way of interacting with the data for a particular session

• in the nifti files in subfolders
• in metadata stored in the variables groups and session that are stored in the mrSESSION.mat file
• in metadata stored in other files (e.g. motion comp matrices, alignment info, etc.) that cannot be stored in nifti files.

mrSESSION.mat

load('mrSession.mat')
% info about the sesion in a struct
session

Simply the metadata that was entered at the mrInit() step - but in a convenient struct and needed so mrTools code can pick this up in various steps internally.

>> session

session = 

    mrLoadRetVersion: 4.7000
         description: 'demo analysis'
             subject: 'S1'
            operator: 'ds'
              magnet: 'Allegra 3T'
                coil: 'LifeService'
            protocol: 'cbi_ep2d_bold: '

Information about groups contains some more useful info about the scans stored in the Raw group. More on how data is stored in groups on this page.
