Re: [ccp4bb] Using SFall for map conversion

Yes, it's "mode sfcalc" in refmac: echo mode sfcalc |\ refmac5 mapin density.map hklout density.mtz As for automating sfall, I've found that using SFSG 1 makes it so all you need to do is make sure the map has the axis order for P1. I have a script that checks for this error and re-runs sfall

Thanks to all. Mapmask works. Yes the order to change to is ZXY. Map from coefficients indeed looks like the directly loaded map, jus the scale is different (I supplied no reference PDB) The remaining issue is - a pain to automate. I tried Refmac- there is a mention of an sfall mode and I trie

Oh…maybe I suggested the wrong order then (Y X Z - for SG 20) ? …I do realize YXZ is not an XYZ cyclic permutation (whereas ZXY is)…I dug it from an old script of mine, so now rechecked the FFT doc …but yes, FFT says that Y X Z is the std axis ordering for SGs higher-than 18…I’m probably missin

Hi Bernhard I don’t know how you actually calculated your map. But it seems as thus it is not following the conventional requirement for the FFT calculation, with regards to the order of the map’s axes (, , , which must be some permutation of X Y Z). This shouldn’t normally happen, except if so

Use mapmask first: echo axis Z X Y |\ mapmask mapin1 old.map mapout new.map For reasons I'm sure made sense at one time, sfall does not seem to know how to automatically re-order the map axes. Also, it is generally a good idea to expand to P1 first, and use "SFSG 1" in sfall.  There are stil

Hi Fellows, I am failing on conversion of a ccp4 map to mtz using Sfall I provide as a scale reference a mtz with FP SIGFP and R free All cell constants and SG 20 and map headers seem to agree. But I receive following warning: *** WARNING - your map spacegroup is different to th

CASP (Critical Assessment of protein Structure Prediction) is in search for targets for the upcoming CASP14 modeling experiment (starting next Monday, May 18, 2020). CASP community experiments aim to advance the state of the art in protein structure modeling. Every other year since 1994, CASP
