Automatic Dmax and profile fitting

August 26, 2020 by Tom Grant

DENSS v1.6.1 now includes new convenience features to automatically estimate the maximum dimension of the particle, Dmax, and perform fitting of the experimental scattering profile.

  • denss.fit_data.py will automatically estimate Dmax when started and calculate an initial profile fit, rather than default to Dmax = 100 Å
  • denss.fit_data.py will now write out additional header lines to the *_fit.dat output file containing parameter values such as Dmax and Rg.
  • denss.py now reads the header from *_fit.dat files, removing the need to explicitly set the -d option
  • if no Dmax is given to denss.py, Dmax will be automatically estimated from the data
  • if raw experimental data are given to denss.py, rather than the expected smoothed/fitted profile, Dmax will be estimated from the experimental data and the data will be fitted with a smooth profile. It is still recommended to manually run denss.fit_data.py first to ensure accurate fitting and Dmax estimation.
