You might want to look into the upsalla compressed mask format (it's an
exact representation of a binary mask - compression is handled by just
tracking the start and end points of the stretches).

Hi,
As I understand, the general molecular mask generated by CCP4 (eg
sfall+mapmask) are binary mask file which needs lots of memory space. I
just wonder whether we can generate some small mask files represented by,
say, envelope function (F(sita,psi))
(http://journals.iucr.org/d/issues/2001/10/00/ba5001/ba5001.pdf). This
will save lots of disc space and lots of efforts for my problem. Thanks!
