Hi there freesurfer experts,
I am fairly new to freesurfer. I am attempting to convert freesurfer overlay files and eventually create individual-specific annotation files which will then be used to create a segmentation file to be used for drawing white matter tracts.
When I run mri_info on the overlay files I get the following:
Volume information for Net_10_ROIs_1_lh.mgh type: MGH dimensions: 253237 x 1 x 1 voxel sizes: 1.000000, 1.000000, 1.000000 type: FLOAT (3) fov: 253237.000 dof: 1 xstart: -126618.5, xend: 126618.5 ystart: -0.5, yend: 0.5 zstart: -0.5, zend: 0.5 TR: 0.00 msec, TE: 0.00 msec, TI: 0.00 msec, flip angle: 0.00 degrees nframes: 1 PhEncDir: UNKNOWN FieldStrength: 0.000000 ras xform present xform info: x_r = 1.0000, y_r = 0.0000, z_r = 0.0000, c_r = 0.5000 : x_a = 0.0000, y_a = 1.0000, z_a = 0.0000, c_a = 1281.0000 : x_s = 0.0000, y_s = 0.0000, z_s = 1.0000, c_s = 0.5000

My initial thought was to run mri_label2label --> mri_label2vol --> mris_label2annot --mri_label2vol --> mri_concat = segmentation in native volume

Any guidance would be greatly appreciated. Thank you!
