Prepare the files

The set of files that are part of the submission are specified using a manifest file. The manifest file is specified using the -manifest <filename> option.

A sequence read submission consists of the following files:

  • 1 manifest file
  • 1 BAM file, 1 CRAM file, or 1-2 Fastq files

Manifest file

The manifest file has two columns separated by a tab (or any whitespace characters):

  • Field name (first column): case insensitive field name
  • Field value (second column): field value

The following metadata fields are supported in the manifest file:

The following file name fields are supported in the manifest file:

CRAM file validation

Reference sequence validation

Reference sequences in CRAM files are required to exists in ENA’s CRAM reference registry.

The Webin command line submission interface maintains two file based caches to avoid unnecessary calls to the registry:

  1. Cache for reference sequence checksums
  2. Cache for reference sequences

The cache for reference sequence checksums is stored in the $HOME/.webin-cli/cram-ref-info directory, where $HOME is the home directory for the user executing the program.

The cache for reference sequences is configured using the REF_PATH and REF_CACHE environmental variables as in samtools.
