Hi, Thomas!
I'd like to ask you some addition questions about FMA. As I understood
from the FMA page that technique is something like integrator of
principal components (merge some PCs with identical functional motion
seen in the X-ray structures for instance) calculated from g_covar. So
FMA is al
Dear all!
I've read some reference papers about EDA sampling methods and found
such usefull things. First of all as I understood for biassing MD
simulation along several PCs extracted from another run the make_edi
-radacc 1-3 option is exactly what I need.
But I havent still understood about m
I've still made such 'only c-alpha ensemble' of my structures by the
other software and performed x-ray PCA. As the result I've extracted
eigenvectors and obtained reasonable distribution (projection) of the
structures along that eigenvectors.
Now I have questions about pca-biassed MD_run. I've ma
I've tried to make PCA from my X-ray data and forced with many problems :)
Firstly I've made pdb trajectory in NMR-like format ( by means of
pymol) consisted of all X-ray structures.
than I've make .tpr file (From the tpr of the same protein which I've
simulated previously) for the subset of C-al

Thomas,
thanks again for explanation. Its also intresting to me is it possible
to do further biassed MD guided on that FMA modes as well as obtain
projections onto that FMA sub-spaces of X-ray datasets for instance ?
( e.g for comparison of the results from FMA of experimental data as
well as MD_d

Thomas,
thank you for the explanation
1) Indeed ED sampling was exactly that I need. It's not quite
understand for me about correct chose of that parameters for biassing
simulation
-linfix string Indices of eigenvectors for fixed increment
linear sampling
I presume you are referring to Essential Dynamics Sampling, described in
section 3.14 of the manual (v4.5.4). There is also a great tool that finds
the few PCs that are maximally correlated to a functional quantity (e.g.
the volume of the active site). The technique is coined Functional Mode
