We are excited to announce the release of DENSS v1.7.0. Included in the updates are many bug fixes, speed and stability improvements. A few new scripts have been added and updated, significant ones including denss.pdb2mrc.py and denss.mrc2sas.py. denss.pdb2mrc.py has been completely rewritten using a new algorithm to calculate electron density maps from atomic models that accurately fit experimental SWAXS data (more details in a follow up post and in our bioRxiv paper). The new script denss.mrc2sas.py is included to fit a calculated scattering profile from a density map to experimental SWAXS data, and calculate χ2 as a metric of the quality of fit. Similar fits are also now produced by denss.py, denss.refine.py, and denss.all.py. This algorithm now produces a .fit file on the same q grid as the experimental data for accurate estimation of χ2, which is useful for publications, reporting statistics, and uploading DENSS reconstructions to the SASBDB.
