<h4>
In order to submit a job you need to provide its name:</h4>
<p>
<img src="static/name.png" style="border:2px solid blueviolet">
<p>
The following three types of simulations can be run with the UNRES server: 
local minimization, molecular dynamics and replica exchange molecular dynamics:
<p>
<img src="static/types.png" style="border:2px solid blueviolet">
<p>
Use the "Save & submit" button to start calculations.
<img src="static/submit.png" style="border:2px solid blueviolet">
<p>
Use the "Refresh" button to check the status of a simulation:
<p>
<img src="static/refresh.png" style="border:2px solid blueviolet">
<p>
until
<img src="static/done.png" style="border:2px solid blueviolet">
<p>
After the server job has been submitted the "waiting in the queue to
start" message will be displayed in the status field, which will subsequently change
to "running",  "postprocessing", and "done". While the job has the "running" 
status, the percentage of job accomplishment is displayed.
It should be noted that the "100%" accomplishment refers to the production
phase of a job, after which the postprocessing phase is triggered which also takes
some time (up to several minutes when making a movie from an MD trajectory is 
requested) and whose progress is not monitored. The page is autorefreshed every 30 sec.
<p>
Any single job can by accessed later (for at least 14 days) using the address of the web page
displayed after job submission: e.g. 
http://unres-server.chem.ug.edu.pl/details1/570cf15fc638493893ece1f011ea0182/984/
<br>
Registered users can save all their jobs and access them later after logging in.
Note that the results will be available for a limited period of time,
depending on the storage space availability (at least 30 days).


<p>
<h4>You can use "Load example data" button before submitting calculations 
to try examples listed below:</h4>

<h4><li>Local minimization of protein A (PDB code:1BDD) structure</h4>

<p>
In this example only the PDB code of the selected protein (1BDD) is input.
<p>
<img src="static/min.png" style="border:2px solid blueviolet">


After energy minimization is accomplished, the UNRES model of the protein, 
its total UNRES energy and superposition on starting structure are displayed.
The interactive <a href="https://github.com/arose/ngl">NGL Viewer</a> is employed, which enables the users to manipulate the structure.

After a (M)REMD run is accomplished, a table showing replica-exchange statistics
(a), plots of histograms of UNRES energy for each temperature (b), a plot of
energy vs. temperature (c), a temperature-colored scatter plot of energy vs. RMSD
(d), and the temperature-colored cumulative plot of rmsd vs. step number for all replicas
(e), and a cumulative plot of walk of the replicas in temperature space (f) are
displayed. The colors corresponding to replica temperatures are shown in panel (c),
while different replicas are colored from black to yellow in panel (f).

<p>
The weighted histogram analysis method (WHAM) is applied to compute the
probabilities of the obtained conformations to occur at particular
temperatures and, consequently, the plots of heat capacity (g) and ensemble-averaged RMSD (h) as a functions
of temperature; these are shown in the respective graphs.

<p>
Note! Panels are labeled in this tutorial only and labels are not displayed 
in the outputs from real server jobs.
<p>
Finally cluster analysis is performed to select 5 families of conformations,
and representative model from each family is converted to all-atom
and refined. Models are shown using NGL Viewer.

This simulation starts from the extended chain, 2000000 steps for each of 16
replicas (8 temperatures with multiplexing 2)
are run and secondary-structure restraints predicted by PSIPRED and 
obtained at the CASP12 time when the experimental 5G3Q structure
was not included in the PDB database are used. The Berendsen thermostat
was employed and the resulting conformational ensemble was clustered 
at the temperature of 290K. 
This is a full-blown structure-prediction run, but shorter
compared to the UNRES runs during the CASP exercises.
