Wont mapmask do that? Find the fraction coordinate of the blob extent then carve that section out of the map? Eleanor >From documentation:
*XYZLIM [ASU] [CELL] [MATCH] <x1> <x2> <y1> <y2> <z1> <z2>**Set the output map extent as `extend'. <x1>-<z2> are given in grid units or in fractional coordinates. It is possible to automatically extend to the CCP4 default asymmetric unit, or a whole unit cell, by specifying `XYZLIM ASU' or `XYZLIM CELL'. It is also possible to extend the map to match another map (given as MAPLIM) by specifiying `XYZLIM MATCH'. The default is to keep the extent of the input map.* On Fri, 29 May 2020 at 08:03, Pavel Afonine <[email protected]> wrote: > Hi Bernhard, > > "Like comparing these map regions, excluding > > intrusion of a solvent mask, etc.": > > You didn't say much about the context..
