Field Documentation

int IMP::em::MRCHeader::mapc

Axes corresponding to columns (mapc), rows (mapr) and sections (maps) (1,2,3 for x,y,z)

int IMP::em::MRCHeader::mode

Image mode.

0 image : signed 8-bit bytes range -128 to 127. 1 image : 16-bit halfwords. 2 image : 32-bit reals. 3 transform : complex 16-bit integers 4 transform : complex 32-bit reals

float IMP::em::MRCHeader::xorigin

extra space used for anything - 0 by default Map origin used for transforms (x dimension)
