LATEST EMAIL UPDATE: 04 May 2014
###################################################################

Here are the main changes (see UPDATES.txt for complete history,
detailes of last 2 updates appended below):

 1) new "label:" button "C" to generate overlap labels.  In
      contrast to the "RC" button (read, re-cut label), this
      cut button does *not* restore currently invisible vertices,
      so doing "C" for 2 or more labels leave the intersection
      (AND) of them, saveable with "W".

 2) add MATLAB "Jet" colorscale (colscale=15, blue/cyan/yellow/red)
      Bounds of scale (dark blue, dark red, clamped beyond) set by
      truncphase entries, accessible on large [fn]-F3 panel and View
      Functional Data as "jt", reversed w/invphase.  Unlike other
      scales, extreme values are dark so best adapted to full rank
      data.  If fthresh/fmid not zero, fades to background.

 3) if tkregister sample policy is "round", add 1/10 micron (0.0001 mm)
      offset to transform to avoid aliasing zoomed voxels at zoom=2.

 4) "R" button on "val:" line now also accepts a 1frame 1D float *.mgh
      file (e.g., output of FSL/freesurfer surface-based pipeline).
      Note that these files typically do not contain indication of
      which hemisphere they came from (if fsaverage, can be read into
      either!).  The "PaintFile:", "StatMask Paintfile:" and "val:"
      dropdowns will be loaded with any available .w or .mgh files.
      The tksurfer read_binary_values command auto-detects magic number
      in valfile or curv, or *.mgh suffix to determine format.

 5) Setup Align/Funct scan accepts conforming (256/512) .mgz file for
      MOVEABLE (for qT1 pseudo 'functional' overlay)

 6) conflicting internal variable name semantics cleanup, csurf vs. C/tcl:
      [hopefully be no visible effect of this!!]
      csurf: $session = "130503MS"
             $scandir = "image/polar1" => change varname to: $iscandir
      C/tcl: $session = "/usr0/fspace/130503MS/image" => varname: $isession
             $scandir = "polar1"

To install:

  cd <dir-where-csurf-currently-installed>
  mv csurf csurf-YYMMDD
  tar xvfz csurf0.8-{mac,linux}-YYMMDD.tgz

cheers,
marty
