Xander Gene-targeted Metagenomic Assembler

Metagenomics can provide important insight into microbial communities. However, assembling metagenomic datasets has proven to be computationally challenging. We present a novel method for targeting assembly of specific protein-coding genes using a graph structure combining both de Bruijn graphs and protein HMMs. The inclusion of HMM information guides the assembly, with concomitant gene annotation.

Required Modules

Serial

  • gcc/5.2.0
  • xander

System Variables

  • HPC_XANDER_DIR - installation directory
  • HPC_XANDER_CONF - base configuration file directory

Additional Information

Configuration File

Xander uses a configuration file which you must manually specify during your run. We provide a basic working configuration file at $HPC_XANDER_CONF/xander_setenv.sh. You must modify the SEQFILE and WORKDIR paths to your working directory.

$ ml gcc/5.2.0 xander
$ HPC_XANDER_CONF/xander_setenv.sh
