Dear Bruce and Freesufers,
I get the following message:
surfer: Interpreting overlay volume /media/EHD/ALLA_FREESUFER_PROCESSING_TIDIS_NOMAS_AD/qdec/lh.kvot_gender.glmdir/Gend/thresholded.mgh as encoded scalar volume.
the two volumes I tried to convert:
1)
Volume information for sig.mgh type: MGH dimensions: 163842 x 1 x 1 voxel sizes: 1.0000, 1.0000, 1.0000 type: FLOAT (3) fov: 163842.000 dof: 0 xstart: -81921.0, xend: 81921.0 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 ras xform present xform info: x_r = -1.0000, y_r = 0.0000, z_r = 0.0000, c_r = 0.0000 : x_a = 0.0000, y_a = 0.0000, z_a = 1.0000, c_a = 0.0000 : x_s = 0.0000, y_s = -1.0000, z_s = 0.0000, c_s = 0.0000

2)

Although both these overlays have significant areas - nothing appears on the binarized version after the conversion
