What it does
Creates a Ramachandran plot for proteins. All protein [φ,ψ] angles for a given segment ID are automatically selected for an entire trajectory and an averaged Ramachandran plot is returned. Optionally the selection can be refined by residue ID or residue name. Optionally the average Ramachandran plot can be deconvoluted and returned grouped by residue name or residue ID.
Input
- Structure file (PDB)
- Trajectory file (DCD).
- Segment ID
- Optionally: Group data by residue name or residue ID
- Optionally: refine selection by residue ID range or residue name (e.g. ALA)
Note that a MDAnalysis 'segment' is a larger organizational unit, for example one protein or all the solvent molecules or simply the whole system.
Output
- Image (as png) of the Ramachandran from MDanalyis with the allowed regions as a background.
- Image (as png) of the Ramachandran plot as a distribution.
- Data (H5 format). All phi, psi timeseries raw data in HDF5 format.
- All plot images tabulated (in html). To view the HTML in Galaxy this tool must be added to the allowlist by a Galaxy Admin.
