I believe there are many advantages to storing things *internally* as data objects with metadata instead of as columns of an MTZ file. How many students know what FP,SIGFP mean? And how many know that the FP,SIGFP columns in Refmac's HKLIN are not the same as the FP,SIGFP columns in HKLOUT? In an interface you can give these much more friendly names such as "observed amplitudes" and "amplitudes scaled by Refmac". The problem is that people should not need to access the *internal *i2 files to get to this data. Currently, you can export mini MTZs (containing only one data object) at the bottom of each report and you can export a full MTZ from Refmac using the Export MTZ button at the top of the interface, but probably this issue can be solved by doing the following:
1. Making sure that reflection data objects have sensible names 2. Expanding the "Export MTZ" functionality to have a customisable selection of any data objects (and allowing customisation of column labels as there may be clashes) Kind regards, Paul On Thu, 16 Mar 2023 at 07:14, Jan Dohnalek <dohnalek...@gmail.com> wrote: > We are hitting the same problems also with students (so no rigidified > brains I think) ... the concept of "files" seems absolutely natural (also > to them) and when they ask about solving more tricky problems in i2 ... we > do the obvious, go back to ccp4i. > > I2 is fine when things are smooth and easy. > > Jan > > > On Wed, Mar 15, 2023 at 3:52 PM Randy John Read <rj...@cam.ac.uk> wrote: > >> Hi Jon, >> >> My understanding of the philosophy is that new users would prefer to >> think about crystallographic data objects, rather than worrying about the >> arcana of MTZ files and the many different flavours of columns.
