You are quite right - LSQKAB must be wrong to report a RMS
Distance?/deviation? for a GLY side chain - will look into it and
correct I hope.. Thanks for noticing it and pointing the bug out

A horrible bug -
this line was somehow lost from lsqkab in the mists of time:
Lines 1029-132 - ish

Hello all,
I have still a question about LSQKAB
Why LSQKAB gives a rmsd (or a rms xyz I don't mind) non null for
glycine side chains ?

Is the rms xyz displacement equivalent to an rmsd??
yes. it is in fact a better name than rms deviation, although i think
'root-mean-square distance' is even better, as it says exactly what you
calculate.
think of it like this, the formula for rmsd
Hello all,

Why LSQKAB gives a rmsd (or a rms xyz I don't mind) non null for glycine

thanks a lot

Sorry for this 'joke-like' question which was not intend to be a joke
There was a misunderstanding about my question
It is not null or not null which worry me, but it is the fact there is a
value for
glycine 'side chains that I know for sure having no side chains.

RMS deviation refers to the variance of a random variable - it is a
characteristic of the underlying probability distribution. When you
superpose two different structures, you
