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 talairach xfm : Orientation : LIA Primary Slice Direction: coronal voxel to ras transform: -1.0000 0.0000 0.0000 81921.0000 0.0000 0.0000 1.0000 -0.5000 0.0000 -1.0000 0.0000 0.5000 0.0000 0.0000 0.0000 1.0000 voxel-to-ras determinant -1 ras to voxel transform: -1.0000 0.0000 0.0000 81921.0000 -0.0000 -0.0000 -1.0000 0.5000 -0.0000 1.0000 -0.0000 0.5000 0.0000 0.0000 0.0000 1.0000 2) Volume information for cache.th13.abs.sig.cluster.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 talairach xfm : Orientation : LIA Primary Slice Direction: coronal voxel to ras transform: -1.0000 0.0000 0.0000 81921.0000 0.0000 0.0000 1.0000 -0.5000 0.0000 -1.0000 0.0000 0.5000 0.0000 0.0000 0.0000 1.0000 voxel-to-ras determinant -1 ras to voxel transform: -1.0000 0.0000 0.0000 81921.0000 -0.0000 -0.0000 -1.0000 0.5000 -0.0000 1.0000 -0.0000 0.5000 0.0000 0.0000 0.0000 1.0000 Although both these overlays have significant areas - nothing appears on the binarized version after the conversion Best wishes, Olof Lindberg Olof Lindberg PhD Novum plan 5 NVS department section clinical geriatrics 14186 Stockholm +46722255711 http://www.oloflindberg.se <https://email.ki.se/owa/redir.aspx?SURL=J0wY4rfFaJiRdznonoXdg3ld1xD2HSpgTJIpfeKTGO_LAthFySfTCGgAdAB0AHAAOgAvAC8AdwB3AHcALgBvAGwAbwBmAGwAaQBuAGQAYgBlAHIAZwAuAHMAZQA.&URL=http%3a%2f%2fwww.oloflindberg.se>
