AllpathsLG 44837

Community rating: ?????

AllpathsLG App that runs on Lonestar.

Quick Start

  • To use AllpathsLG 44837, import your sequencing reads in fastq format. Enter paired reads in the paired read sections. All libraries must have a name. All paired libraries must have an entry for pair distance and the estimated error in this value. The type of library should be entered - fragment or jumping. Usually this setting will determine the orientation of the reads, but the Reads 4 section requires a setting for orientation and allows the unlikely situation that fragment reads are not forward-reverse or jumping reads are not reverse-forward. Set the time according to expected run. Maximum memory available with be 1 TB. Maximum run time 48 hours, so large genomes will not likely assemble in that time. If indications are that that is a limiting factor, you can try Random downsample reads to reduce the load. Be sure to enter a value for sequence format for each library (fragment, jumping respectively).

Test Data


Test data for this app appears directly in the Discovery Environment in the Data window under Community Data -> iplantcollaborative -> example_data -> allpaths -> rhodo.

Input File(s)

Use the "frag" reads (180 bp spacing, +- 30) as a fragment library labeled "fragment" (or anything really) from the directory above as test input. Use the "shortjump" reads (3500 bp spacing, +- 500) as a jumping library labeled "jumpie". Run for 4 hours. Check "Override Phred" to make sure the assembly isn't stopped because of questions about the Phred setting. 

Output File(s)

Outputs will include a genome.scf.fasta file for the scaffolds, and a genome.ctg.fasta for contigs.
