----------------------------------------------
Illuminate inside of a surface
----------------------------------------------

The inside of a surface (backside of a flat
patch), which is rarely visible, is not normally
lit.  To illuminate the inside of a surface, use
ctrl-middle-click-REDRAW.  This is now
automatically done when using PLANE to cut a
surface, and it useful in other rare circumstances
(e.g., better view of a cut, folded cerebellar
surface :-} ).

----------------------------------------------
Display MGH 3D segmentation colors in tkmedit
----------------------------------------------

The standard 6-column MGH FreeSurfer color lookup
table (idnum, name, r, g, b, a) is now used in
tkmedit to display MGH 3D segmentation labels
(either byte or int) in their proper colors:

  $CSURF_DIR/lib/lut/FreeSurferColorLUT.txt

The color table is read, sorted, and loaded by new
C/tcl function, read_sort_mghval2rgblut.  The
existing csurf function, read_val2rgblut, which
reads 4-column csurf color tables designed for
color interpolation of overlay stats (value, r, g,
b), defaults to the new function if it detects the
standard name above.

This all occurs automatically when an MGH
segmentation file (e.g., aseg+aparc.mgz) is
selected in the "im2:" entry dropdown and read
using the adjoining "R".  Once read, a
double-middle-click on the image window displays
the name, idnum, and rgb of a labeled region.

The "la" tickbox toggles the visibility of the
label overlay.

The "tran:" entry on the large F4 tkmedit
interface ([fn]-F4 in the tkmedit buttons window)
controls the label transparency (default is 127,
which is 50%).

----------------------------------------------
Dump timecourses using MGH 3D segmentation in tkmedit
----------------------------------------------

A new tkmedit C/tcl function:

  write_segid_timecourses <idnum>

dumps rawdata timecourses for an MGH FreeSurfer
segmentation region (idum).  After opening a
rawdata-containing scan using VOLUME-STATS, read a
segmentation file, enter the idnum of a region in
the "roiup:" entry, and middle-click the "T"
button.

This generates an ASCII file, for example,

  segid-12120.raw

containing the time courses of any rawdata voxels
in that region.  This file also includes the
number of 'hits' for each voxel (since the rawdata
voxels are typically larger than 1x1x1mm
segmentation voxels).

----------------------------------------------
Dump all MGH 3D segmentations to BRIK
----------------------------------------------

A new tkmedit C/tcl function:

  write_allsegids

creates an AFNI BRIK containing the int idnums
from every 3D region in the currently loaded MGH
FreeSurfer segmentation.  This BRIK has the
resolution of the underlay (typically 1x1x1mm).

----------------------------------------------
Temp fix for tksurfer going black after first click
----------------------------------------------

On a default CentOS 7 install, with onboard
unaccelerated graphics libs, tksurfer goes black
after the first click on the surface, afterwards
only showing the selected vertices.  As a tmp fix,
in this case, csurf starts up tksurfer (on 3.0+
kernel Linux) in singlebuffer mode, which will
still look doublebuffered :-}

For tksurfer started from the command line, fix
this problem by turning off doublebuffering with
an option (argument is a "zero") as follows:

  tksurfer <name> <hemi> <surfext> -doublebufferflag 0 [-opts ...]

Better fix in progress!  If the 'intelligence' in
csurf (e.g., OK to use doublebuffer if nvidia
driver found to be in use) makes the wrong choice
(e.g., still black screen, or alternatively, you
see the redraws when you move the brain), you can
force csurf to use single- or double-buffered
startup of tksurfer with:

  csurf -sb
  csurf -db

----------------------------------------------
Linux fonts fixed
----------------------------------------------

The unpleasant looking (to me!) default Linux
fonts in csurf, tksurfer, tkmedit, and tkregister
are now finally fixed (made the same as on Mac).
The nicer looking fonts are slightly larger and
easier to read than before.

In the unlikely event you like the way they
looked before, to go back, find the following
line in your FreeSurferEnv startup script:

  FreeSurferEnv.sh   =>  #skipfontsflag=1
  FreeSurferEnv.csh  =>  #set skipfontsflag = 1

and comment it in (rm the '#').

----------------------------------------------
Display color phase contour over dark overall activation
----------------------------------------------

The original phasemovie.tcl shows a moving phase
contour in white over the colored phase map.  The
phasemovie.tcl script popup can now invert this.
Ticking colphasecontourflag on the popup (which
sets $colphasecontourflag to 1) causes the phase
stripe to be colored (with its usual phase color)
while the remainder of the activation that is not
at the (adjustable) phase range of the stripe is
given the same color controlled by the variable
$phasecontour_bright.  This is like movie in Chen,
Kreutz-Delgado, Sereno, Huang (2018).

To make the moving colored phase stripe clearly
visible, use a dark color for the overall
activation (phasecontour_bright = 20; this is
autoset when colphasecontourflag ticked).

-----------------------------------------------
Bug fixes, small changes
----------------------------------------------

add tksurfer -justheaderflag (after mris_info OS crash on read cereb)

tksurfer/tkmedit upper-left "i" buttons to control interface size

Patch tk raise command for Linux (raise tools win w/double-clk surf win)
  CentOS 5 -> was fail
  CentOS 6 -> was fail
  CentOS 7 -> was fail w/giant, empty, upper-right popup

fixed FRED_TONO wraparound bug

many small helpfile updates

all standard tcl scripts now have R-click help from popup

fix bash navigation aliases (e.g., cds <subj> => cd to subject's scripts)

new function: norm_move_vertices_fracthick <frac>
