Dear all,

Thanks to quite a few community members who responded, these are the tips:
1) PDB staff has graciously replied with some essential news that I've
missed (see below); 2) mtz files (and more) could be downloaded from
https://pdb-redo.eu/; 3) In coot, instead of using the "Fetch PDB and Map
using EDS", one may simply use the next functionality on the pull-down
menu, which is "Fetch PDB and Map using PDB-Redo".


*The EDMAPS.rcsb.org <http://edmaps.rcsb.org/> service for mtz files was
retired on October 16, 2024 (see previous announcement
<https://www.rcsb.org/news/feature/663baab365d8a8cacaf76fa4>. This service
had been providing RCSB PDB-calculated electron density map coefficients
for X-ray structures in the PDB archive. In June, this service stopped
providing DSN6 formatted maps for these structures.*

*Electron density map coefficients will instead be provided by wwPDB for
all X-ray structures in the PDB archive. These map coefficients will be the
same as those used in wwPDB Validation Reports.*

*For more information, see the news item
