Sorry, I was wrong about using STDEV in Excel. Instead you would need to put in a formula to calculate the root mean square of your distances. On Tuesday, 17 September 2019, 15:14:02 BST, Jonathan Cooper wrote: I think LSQKAB can output a list of CA distances of two structures. Might

Hi, (good old) LSQMAN from the Uppsala Software Facotry will do this for you. First you align the structures based on the subset of atoms you want to match, then use the RMSD command to calculate the rmsd for the subset of atoms you are interested in. Best wishes, Massimo -- Dr. Massimo Degan

I think LSQKAB can output a list of CA distances of two structures. Might be easier to fit them first in Coot since LSQKAB can be a pig to run and you may have to use the command line. You could then select the region(s) you are interested in and use a spreadsheet or a script to calculate the RM
