Building Web UIs With Mojolicious Perl

Jit — Tue, 26 Dec 2017 18:06:57 -0600

Mojolicious is one of 3 leading web frameworks available in the perl ecosystem (along with Dancer and Catalyst) and by far my favorite.

Mojolicious aims to provide a complete web development experience. It thus has no hard dependencies, comes with a built-in development and production server and many other features one needs to build a web application. It's easy to install, has an applciation generator script and many plugins and extensions.

Libraries for developing Web applications

Amon2
Catalyst - Overflowing with features. Very popular.
Dancer (Official site)
Dancer2
Gantry - Web application framework for mod_perl, cgi, etc.
Kossy - A Web framework with simple interface.
Mojolicious - An all in one framework.
Poet - a modern Perl web framework for Mason developers

Unicycler: Hybrid assembly pipeline for bacterial genomes

Jit — Fri, 10 Nov 2017 03:58:27 -0600

Unicycler is an assembly pipeline for bacterial genomes. It can assemble Illumina-only read sets where it functions as a SPAdes-optimiser. It can also assembly long-read-only sets (PacBio or Nanopore) where it runs a miniasm+Racon pipeline. For the best possible assemblies, give it both Illumina reads and long reads, and it will conduct a hybrid assembly.

MMseqs2.0: ultra fast and sensitive protein search and clustering suite

Jit — Thu, 22 Mar 2018 10:40:51 -0500

MMseqs2 (Many-against-Many sequence searching) is a software suite to search and cluster huge protein sequence sets. MMseqs2 is open source GPL-licensed software implemented in C++ for Linux, MacOS, and (as beta version, via cygwin) Windows. The software is designed to run on multiple cores and servers and exhibits very good scalability. MMseqs2 can run 10000 times faster than BLAST. At 100 times its speed it achieves almost the same sensitivity. It can perform profile searches with the same sensitivity as PSI-BLAST at over 400 times its speed.

The MMseqs2 user guide is available as Github Wiki or as PDF file (Thanks to pandoc!)

WhatsHap: fast and accurate read-based phasing

Jit — Mon, 28 May 2018 09:52:16 -0500

WhatsHap is a software for phasing genomic variants using DNA sequencing reads, also called read-based phasing or haplotype assembly. It is especially suitable for long reads, but works also well with short reads.

Features

Very accurate results (Martin et al., WhatsHap: fast and accurate read-based phasing)

Works well with Illumina, PacBio, Oxford Nanopore and other types of reads

It phases SNVs, indels and even “complex” variants (such as TCG → AGAA)

Pedigree phasing mode uses reads from related individuals (such as trios) to improve results and to reduce coverage requirements (Garg et al., Read-Based Phasing of Related Individuals).

WhatsHap is easy to install

It is easy to use: Pass in a VCF and one or more BAM files, get out a phased VCF. Supports multi-sample VCFs.

It produces standard-compliant VCF output by default

If desired, get output that is compatible with ReadBackedPhasing
