-------------------------------------------
entry variable: $statpatt -- native stats file
-------------------------------------------
default: */scandir1/scan1_r_%03d.bfloat

The "valn:" entry shows the name of the current
native-resolution 3D statistical amplitude (val)
overlay file.  This will have been loaded,
registered to, and upsampled to structural
resolution if tkmedit was started from csurf with
the View Functional Data panel VOLUME-STATS
button.

Session directory can be abbreviated as an
asterisk (*).  Absolute name OK, too.  Relative
name appended to session.

Examples:

  pol1-vreg_r+orig.BRIK
  pol1-vreg_i+orig.BRIK
 
  pol1-vreg_r_%03d.bfloat
  pol1-vreg_i_%03d.bfloat

Requires float data (float BRIK or bfloat file
set).

Contains real-valued activations, complex-valued
activations, or a statistical mask, all of which
are at native (typically EPI) resolution.

If the file infix immediately before +orig.BRIK
(or _%03d.bfloat) is either "_r" or "_x", and the
data is complex-valued as determined by "cpx"
being ticked ($complexvalflag=1), an attempt will
also be made to also read the corresponding "_i"
or "_y" BRIK file (by tcl funct readnativestat).
