283658 (current)	2023-05-10	cod/ (saulius@tasmanijos-velnias) Estimating atom types and attached hydrogen counts using the new cod-tools scripts [1], for those AMCSD files that had Wat or O-H or OW atoms, and where declared and computed formula matches after the update. Several files were spotted manually where attached hydrogen counts will need to be updated to match the title formula. The update command was: 553 ( set -x; directory-metadata; grep ^9 formula-with-estimated-atoms-all.tsv \| grep = \| awk '{print $1}' \| sort -u \| codid2file \| xargs -i bash -c 'Z=$(cifvalues --no-dataname --tag _cell_formula_units_Z {}); if [ $Z = "?" ]; then NEW_Z=$(cif_estimate_Z {}); fi; cif_guess_AMCSD_atom_types {} \| (if [ $Z = "?" -a -n "$NEW_Z" ]; then cif_select --invert --tag _cell_formula_units_Z \| cat - <(echo _cell_formula_units_Z $NEW_Z); else cat; fi) \| cif_filter --add-cif-header {} \| sponge {}; echo Updated: {}'; date ) &> update-files-with-matching-formulae.log & run in the working copy of the repo [2].
