I think Peter touches the point that we discussed previously, and this is
one more reason to think about it in practical terms : it would be nice if
phenix has an alternative option NOT to build a mask from the model but to
read it outside. For example, it may be an EM envelope, or a mask built by
any automated procedure.
An intermediate option is that indeed phenix gives a procedure to
fill an external mask by dummy atoms with occ=0 and then you add them to
you "regular" model and build the mask by your usual procedure. Would it be
easier and faster ?
I understand that any solution requires your personal time (as
usually, your initial time estimations multiplied by 10 :-)
Best regards,
Sacha
