[MINC-users] register and [0-1] float volumes

[Vladimir S. FONOV]

Hello,


it looks like new patches are not quote ready for general use. I updated 
all the subprojects in minc-toolkit-v2 to the latest develop heads and 
rebuilt register. And I am getting following results:


1. running register on a float volume with range 0-8.57 - i have old 
behavior (i.e all the values between 0 and 1.0 are mapped to black)

2. running minccalc -express 'A[0]/10' test1.mnc test2.mnc (test2.mnc 
now have range 0 - 0.857) , followed by register test2.mnc - works 
properly .

3. running register test2.mnc test2.mnc results in segfault, register 
test1.mnc test1.mnc still works.

4. running minccalc -express 'A[0]*10' test2.mnc test3.mnc,
register test3.mnc - works, but with old behavior
register test3.mnc test3.mnc segfaults.
