What are the local scores in qmeanbrane?
The local scores are a linear combinations of the 4 statistical potential terms as well as the agreement terms evaluated on a per residue basis. They are as well in the range [0,1] with one being good. QMEANBrane is a version of QMEAN developed to assess the local quality of alpha-helical transmembrane protein models.
What is the range of the qmean4 scores?
They all provide scores in range [0,1] with one being good. QMEAN4 is a linear combination of four statistical potential terms. It is trained to predict global lDDT score in range [0,1]. The value displayed here is transformed into a Z-score to relate it with what one would expect from high resolution X-ray structures.
What is the difference between qmean4 and qmean6?
There are two global score values, QMEAN4 and QMEAN6. QMEAN4 is a linear combination of four statistical potential terms. QMEAN6 additionally uses two agreement terms evaluating the consistency of structural features with sequence based predictions.
What is the qmeandisco global score and error estimate?
The QMEANDisCo global score is the average per-residue score and the provided error estimate is based on global QMEANDisCo scores estimated for a large set of models and represents the root mean squared difference ( i.e. standard deviation) between QMEANDisCo global score and lDDT (the ground truth).
What is a good Qmean score?
QMEAN z-scores around zero indicate good agreement between the model structure and experimental structures of similar size. Models of low quality typically have scores of -4.0 or lower. The “thumbs-up” and “thumbs-down” symbols next to the score are used to indicate whether or not the model is of good quality (9).
What is GMQE score?
GMQE (Global Model Quality Estimation) is is expressed as a number between 0 and 1, reflecting the expected accuracy of a model built with that alignment and template, normalized by the coverage of the target sequence. Higher numbers indicate higher reliability.
How does SWISS-MODEL work?
How does the Swiss model work? Under a Swiss model-style system, teams play a set number of games rather than facing every other team in the league. In the case of the proposed 36-team Champions League, clubs are set to play 10 matches against opponents determined by a seeding system.
Why is SWISS-MODEL used?
SWISS-MODEL is a structural bioinformatics web-server dedicated to homology modeling of 3D protein structures. Homology modeling is currently the most accurate method to generate reliable three-dimensional protein structure models and is routinely used in many practical applications.
How can I become a Swiss-model?
How build a model using the DeepView Project ModeGet the template in the correct quaternary state. First, check the correct biological assembly of your template protein. ... Remove all non-amino acid residues. ... Ensure unique chain IDs. ... Target sequence. ... Adjust target–template alignment in DeepView. ... SWISS-MODEL submission.
Why is homology Modelling important?
Homology modeling obtains the three dimensional structure of a target protein based on the similarity between template and target sequences and this technique proves to be efficient when it comes to studying membrane proteins that are hard to crystallize like GPCR as it provides a higher degree of understanding of ...
What is the UEFA SWISS-MODEL?
So what is the "Swiss model"? Rather than teams being drawn into eight groups of four, as is the case now, all clubs are placed into one giant table. It is based on the Swiss-system tournament used in chess, whereby each team does not play all of the others.
What is Swiss league format?
A Swiss tournament is similar to a Round-Robin tournament in that no players are eliminated. Every player will play every round, and the player with the highest number of points at the end of the tournament is the winner.
What is Swiss PDB?
Swiss-PdbViewer (aka DeepView) is an application that provides a user friendly interface allowing to analyze several proteins at the same time. The proteins can be superimposed in order to deduce structural alignments and compare their active sites or any other relevant parts.

1. Introduction
Estimating the quality of protein structure models is a vital step in protein structure prediction. Often one ends up in having a set of alternative models ( e.g. from different modeling servers or based on alternative template structures and alignments) from which the best candidate shall be selected.
3. Input Format Requirements
Either a model in PDB format or tar.gz -archives with multiple models in PDB format sharing the same reference sequence (SEQRES) can be uploaded.
4. Input Data Processing
Local qualities are visible as color gradients in the model viewer. They additionally get mapped onto the structures available in the downloadable archives as bfactors. The server provides you with two alternative structures in the archives that undergo certain processing steps.
5. Programmatic Access
One can access QMEAN-SERVER programatically with provided API. In order to use QMEAN submission API you have to make a POST request to the https://swissmodel.expasy.org/qmean/submit/ with following parameters. (Parameters "structure" and "email" are required)
