Synteny Portal: a web-based application portal for synteny block analysis

Jit — Wed, 24 May 2017 10:39:23 -0500

Synteny Portal, a versatile web-based application portal for constructing, visualizing and browsing synteny blocks. With Synteny Portal, users can easily (i) construct synteny blocks among multiple species by using prebuilt alignments in the UCSC genome browser database, (ii) visualize and download syntenic relationships as high-quality images, (iii) browse synteny blocks with genetic information and (iv) download the details of synteny blocks to be used as input for downstream synteny-based analyses, all in an intuitive and easy-to-use web-based interface. We believe that Synteny Portal will serve as a highly valuable tool that will enable biologists to easily perform comparative genomics studies by compensating limitations of existing tools. Synteny Portal is freely available at http://bioinfo.konkuk.ac.kr/synteny_portal.

splitbam: splits a BAM by chromosomes

Jit — Tue, 28 Feb 2017 09:01:28 -0600

splitbam splits a BAM by chromosomes.

Using the reference sequence dictionary (*.dict), it also creates some empty BAM files if no sam record was found for a chromosome. A pair of 'mock' SAM-Records can also be added to those empty BAMs to avoid some tools (like samtools) to crash.

Usage

java -jar splitbam.jar -p OUT/__CHROM__/__CHROM__.bam -R ref.fasta (bam|sam|stdin)

Options

-h help; This screen.
-R (indexed reference file) REQUIRED.
-u (unmapped chromosome name): default:Unmapped
-e | --empty : generate EMPTY bams for chromosome having no read mapped
-m | --mock : if option '-e', add a mock pair of sam records to the empty bam
-p (output file/bam pattern) REQUIRED. MUST contain __CHROM__ and end with .bam
-s assume input is sorted.
-x | --index create index.
-t | --tmp (dir) tmp file directory
-G (file) chrom-group file (see below)

SCFBio have developed Sanjeevini

Jit — Fri, 17 Nov 2017 07:55:49 -0600

SCFBio have developed a new android based application for drug design called Sanjeevini (https://play.google.com/store/apps/details?id=com.sanjeevini&hl=en). It is available free of charge. You can download it using Google play store. Just search for "Sanjeevini-SCFBIO-CADD" in Google play store. It contains all modules used by current Sanjeevini users. We have worked towards making a unified and easy to use interface. The app now supports all major small molecule file formats (pdb, mol, sdf, mol2 and xyz). The application contains inbuilt visualizer JSmol for easy analysis of results. Users can now directly download the protein files from PDB ("Get protein PDB file" in `FILE` Menu) and prepare it using the easy to use in-built module "Prepare protein/DNA".

SCFBio have worked towards making the process of Job retrieval more streamlined and user friendly. All jobs are now recorded in the "Job results". It can be accessed using the main page of the application. Job status can now be retrieved by clicking on the refresh button against the job ID.

SCFBio have also added a new feature of accessing Jobs run on different android application. Users can retrieve jobs run by other users by sharing the job ID and module name. This feature can be accessed using the Import Jobs option in File menu. We hope this feature will help collaborating groups stay in touch with each other.

The module contains all modules of Sanjeevini suite of software for structure based Drug design.

Sl No.	Module name	Activity
1	Prepare Protein/DNA	Prepares protein/DNA for other modules of Sanjeevini
2	Prepare ligand	Prepares ligands for other modules of Sanjeevini
3	Active site Prediction	Predicts biologically relevant sites in a protein
4	ParDOCK	Rigid Docking of Protein-Ligand complex
5	BAPPL	Binding affinity prediction of Protein-Ligand complex
6	BAPPL Z	Binding affinity prediction of Protein-Zinc-Ligand complex
7	DNA ligand Docking	Rigid Docking of DNA-Ligand complex
8	PreDDICTA	Binding affinity prediction of DNA-Ligand complex
9	SOM Prediction	Rigid Docking of Ligand and CYP proteins
10	Lipinski filters	Checks Lipinski's rule of five for ligand molecule
11	Molecular volume	Calculates volume of a ligand
12	RASPD	Virtual screening of protein molecule to yield hit molecules
13	AADS	Prediction and docking of top 10 biologically relevant sites on protein
14	Intercalate	Rigid Docking of DNA-Ligand complex in intercalation sites
15	DNA sequence to str.	Converts DNA sequence to DNA structure (A-DNA or B-DNA)
16	NRDBSM	Non-redundant database of small molecules
17	TPACM4	Partial charge calculator for small molecules
18	Wiener index	Wiener index calculator for small molecules

The results can be downloaded to the PC desktop for further analysis. For this you can use this accompanying website for this purpose:

CLgenomics

Radha Agarkar — Fri, 03 Mar 2017 09:57:28 -0600

CLgenomics is a standalone desktop software specifically designed for bacterial genome analysis. This program has a powerful multi-genome browser, which enables rapid and responsive exploration of bacterial genomes.

To use CLgenomics, individual genome data (genome sequences + annotation details) are compiled and saved in a specially formatted file called CLG (ChunLab Genomics). Each CLG file corresponds with one bacterial genome. If multiple genomes are being considered and compared, multiple CLG files are needed. ChunLab offers >40,000 CLG files of publicly available Bacterial and Archaeal genomes.

MaxBin: software for binning assembled metagenomic sequences based on an Expectation-Maximization algorithm.

Jit — Mon, 06 Mar 2017 04:03:38 -0600

MaxBin is software for binning assembled metagenomic sequences based on an Expectation-Maximization algorithm. Users can understand the underlying bins (genomes) of the microbes in their metagenomes by simply providing assembled metagenomic sequences and the reads coverage information or sequencing reads. For users' convenience MaxBin will report genome-related statistics, including estimated completeness, GC content and genome size in the binning summary page.

Users can use MEGAN or similar software on MaxBin bins to find the taxonomy of each bin after the binning process is finished.

https://academic.oup.com/bioinformatics/article/32/4/605/1744462/MaxBin-2-0-an-automated-binning-algorithm-to

The most recent version of MaxBin is 2.2, which supports the analysis of coassemblies of multiple samples. It is available at this JBEI downloads sites as well as MaxBin and MaxBin 2.0 sourceforge sites.

In an attempt to find a good Linux reference for bioinformatician and BOL readers, I was unsuccessful at finding a decent one on the Internet. So, we decided to make a cheat sheet for biological programmers.

GroopM: Metagenomic binning toolset

Jit — Tue, 07 Mar 2017 08:59:45 -0600

GroopM is a metagenomic binning toolset. It leverages spatio-temoral
dynamics (differential coverage) to accurately (and almost automatically)
extract population genomes from multi-sample metagenomic datasets.

GroopM is largely parameter-free. Use: groopm -h for more info.

For installation and usage instructions see : http://ecogenomics.github.io/GroopM/

Krona

Jit — Wed, 22 Mar 2017 04:47:35 -0500

Krona allows hierarchical data to be explored with zooming, multi-layered pie charts. Krona charts can be created using an Excel template or KronaTools, which includes support for several bioinformatics tools and raw data formats. The interactive charts are self-contained and can be viewed with any modern web browser (see Browser support).
