RNA QUality Assessment tool (RNAQUA) is RESTful web service client developed in Java using Jersey providing a set of web services designed initially for RNAssess to support quality assessment of RNA 3D structures. At the input, RNA 3D structures must be introduced in PDB format. First, a comprehensive validation of input RNA 3D structure(s) is performed and all identified inconsistencies are reported to a user. An output is returned in XML format using JAXB. Features of the tool include:
- A single 3D structure-based analysis.
- A comprehensive validation of the input RNA 3D structure(s) to report all PDB format inconsistencies (PDB-VALIDATION).
- A computation of an overall clash score (CLASH-SCORE), i.e., number of bad overlaps per 1000 atoms, provided by MolProbity.
- A sequence-based analysis allowing to investigate a sequence of RNA 3D structure(s) (SEQUENCE) or a set of incontinuous RNA 3D substructures specified by the user (FRAGMENT).
- An extraction (ORIGINAL-3D) and unification (RENUMERATED-3D) of RNA 3D structure(s) useful during analysis of input RNA 3D models or a set of incontinuous 3D substructures differing in sequence, distribution of chains, and numbering of residues.
- Analysis of 3D model(s) within the reference structure context.
- A computation of the following measures: Root-mean-square deviation (ROOT-MEAN-SQUARE-DEVIATION), Interaction network fidelity (ALL-INTERACTION-NETWORK-FIDELITY-SCORES-AT-ONCE, INTERACTION-NETWORK-FIDELITY-WATSON-CRICK, INTERACTION-NETWORK-FIDELITY-NON-WATSON-CRICK, INTERACTION-NETWORK-FIDELITY-STACKING, INTERACTION-NETWORK-FIDELITY-ALL), Deformation index (DEFORMATION-INDEX), P-value (P-VALUE), all scores at once (ALL-SCORES-AT-ONCE).
- A sequence-based comparison performed between input RNA 3D model(s) (SEQUENCE) or a set of incontinuous 3D substructures specified by the user (FRAGMENT) and the corresponding 3D structure/substructures of the reference to investigate disturbances in the compared sequences.
- An extraction (ORIGINAL-3D) and unification (RENUMERATED-3D) of RNA 3D model(s) or a set of incontinuous 3D substructures specified by the user which are additionally superimposed over the corresponding 3D structure/substructures of the reference. At the output, ZIP archive including the coordinates of the reference structure as well as all considered RNA 3D model(s) is returned.
- A generation of Deformation profile (DEFORMATION-PROFILE) provided by DPS_1.0.1 which was made available by Jose Almeida Cruz and Eric Westhof.
- To ensure robustness of quality assessment process a user can specify the appropriate alignment (-a,--alignment) between the reference 3D structure and all analyzed RNA 3D model(s) which often differ slightly in sequence, distribution of chains or numbering of residues. An example of alignment prepared between the reference structure (solution.pdb) and a single RNA 3D model (model.pdb) is presented below. This alignment considers two incontinuous 3D substructures. Moreover, there is also incompatibility of chain id between compared 3D structures. Each substructure is described by id of its first residue [i.e., chain id + '_' + residue serial number + '_' + insertion code (if needed)] and length. To integrate many 3D substructures within a single alignment prepared for the particular RNA 3D structure(s) their descriptions are separated by '|'. Alignments prepared for the reference structure as well as the analyzed RNA 3D models combined into a single string are separated by ';'. Alignment prepared for the reference structure should be always included at the beginning of this string.
solution.pdb:A_1,31|A_33,29;model.pdb:U_1,31|U_33,29- For all supported commands, a user can analyse both a single 3D model and many 3D models stored in the same directory at once.
RNAQUA uses the following external open source projects, namely:
- Jersey - framework for developing RESTful Web Services and their clients in Java that serves as a JAX-RS (JSR 311 & JSR 339) Reference Implementation,
- Java Architecture for XML Binding - a library providing a fast and convenient way to bind XML schemas and Java representations to incorporate and process easily XML data,
- Project Lombok - a library allowing for compilation and building of a boilerplate-free code,
- jarchivelib - an easy-to-use API layer on top of the org.apache.commons.compress.
RNAQUA is available in the public repository on GitHub.
To build the RNAQUA package one must have installed:
- stable release of [Oracle JDK 7] jdk (recommended) or above,
- stable release of [Apache Maven 3.2.3] mvn or above,
- stable release of Git git.
A used version of Java can be configured by setting the JAVA_HOME environment variable.
git clone https://github.com/mantczak/rnaqua.git rnaqua
cd rnaquabuild-and-tests.bat
build-only.bat
According to configuration of Linux/Mac machine (when maven3 package is installed, and 'No command mvn found') might be a need to add 'mvn3' symlink to 'mvn'.
chmod u+x build-and-tests.sh
./build-and-tests.shchmod u+x build-only.sh
./build-only.shThe tool provides the following analysis modes: (1) a single 3D structure-based analysis, (2) analysis of 3D model(s) within the reference structure context.
