Ensembl Metazoa scripts for loading ad-hoc annotations

Prerequisites

The whole thing is intended to be run inside the Ensembl production environment. It tries to get local copies of all the Ensembl repos it needs. Please, make sure you have all the proper credential, keys, etc. set up.

Installation, sample configuration and run

Simple actions:

1. Getting this repo

  git clone git@github.com:Ensembl/ensembl-production-metazoa.git

2. Creating (or copying and modifyingi example) meta configuration file (see below).

  ENS_VERSION=105
  mkdir -p ensembl-production-metazoa/meta/$ENS_VERSION
  cp ensembl-production-metazoa/meta/104/dmel ensembl-production-metazoa/meta/$ENS_VERSION
  # edit ensembl-production-metazoa/meta/$ENS_VERSION/dmel if needed

3. Choose/create path for data

  mkdir -p data

4. Run either locally (under either tmux or screen)

    ENS_VERSION=105 MZ_RELEASE=52 \
    CMD=<DB server alias to build at> \
    PROD_SERVER=<DB server alias to production server> \
      ./ensembl-production-metazoa/scripts/mz_generic.sh ensembl-production-metazoa/meta/105/dmel

You'll see a lot of messages (shell trace mode is on by default) on the screen. Don't panic.

Or with LSF (i.e. see ensembl-production-metazoa/meta/flybase.tmpl):

export PROD_SERVER=<DB server alias to production server>
export CMD=<DB server alias to build at>
# or source proper ensembl-production-metazoa/conf/_mz.conf file

export ENS_VERSION=105
export MZ_RELEASE=52
export LSF_QUEUE=<lsf_queue_name>

METACONF_DIR=ensembl-production-metazoa/meta/105

mkdir -p logs locks
ls -1 $METACONF_DIR/d* |
  perl -pe 's,.*/,,' |
  xargs -n 1 echo > sptags

cat sptags | grep -vF '#' | head -n 3 |
  xargs -n 1 echo |
  xargs -n 1 -I XXX -- sh -c \
    "sleep 10; \
     bsub -J load_XXX -q '$LSF_QUEUE' -M 32000 -R 'rusage[mem=32000]' -n 1 \
          -o logs/XXX.stdout -e logs/XXX.stderr \
          flock -n locks/XXX \
            ./ensembl-production-metazoa/scripts/mz_generic.sh ${METACONF_DIR}/XXX ; \
     sleep 7200"

# N.B. A second argument can be passed to/mz_generic.sh, i.e. one of the following:
#        restore pre_final_dc finalise
#      (see docs/mz_generic_params.md for the full list)

In this case you'll have to use tail -f logs/*.stderr or any other way to peek into logs.

Instead of setting each environment variable to configure mz_generic.sh run, you can either create a copy and edit conf/_mz.conf specifying each parameter, or set a single variable with the path to the config MZ_CONFIG=<path_to_conf_file> (see "Parameters for mz_genenic runner" for more details).

While running

5. The first time the process runs it tries to get all the needed Ensembl repos into ${SCRIPTS_DIR}/ensembl.prod.${ENS_VERSION} directory (SCRIPTS_DIR is pwd by default).

If you need to load environment used for building you can

source ${SCRIPTS_DIR}/ensembl.prod.${ENS_VERSION}/setup.sh

6. When script runs it creates

• ${DATA_DIR}/<meta_name>/bup -- to store most recent core backup (usually, created after each stage by backup_relink wrapper)
• ${DATA_DIR}/<meta_name>/done -- each stage stores _<done_tag> in this dir and checks if the tag exists before the run. Thus you can run the same command many times and only unfinished stage will be rerun (no automatic snapshot restoration is performed, see below)
• ${DATA_DIR}/<meta_name>/data/raw -- to store initially retrieved sequence and model data (i.e. FASTAs and GFF from GenBank). It's better to fetch it only once and preserve between reruns (thus try not to delete ${DATA_DIR}/<meta_name>/done/_get_asm_ftp file)
• ${DATA_DIR}/<meta_name>/data/pipeline_out -- to store logs/intermediate files for pipelines that are run. Usually, there's a _continue_pipeline file with instructions on how to connect to/ continue the pipeline
• ${DATA_DIR}/<meta_name>/metadata -- preprocessed metadata to be passed to the run_new_loader stage (new-genome-loader pipeline)

If script stops

7. If anything fails script terminates by default.

• You can either continue pipeline. Source ${SCRIPTS_DIR}/ensembl.prod.${ENS_VERSION}/setup.sh, use the corresponding _continue_pipeline file. (Don't forget to finalise accomplished stage with corresponding _done_tag as written in the file).
• Drop as many ${DATA_DIR}/<meta_name>/done tags as you need (use ls -lt to sort tags by time). Drop as many ${DATA_DIR}/<meta_name>/bup snapshots as you need (none, ideally) and don't forget to refresh the sym link to point to the latest good one. Run ensembl-production-metazoa/scripts/mz_generic.sh with additional second command line option restore:

./ensembl-production-metazoa/scripts/mz_generic.sh ${METACONF_DIR}/<meta_conf_file> restore

Now you can rerun the initial (without restore) build command once again.

8. Sometimes the script stops as planned. In this case edit the raw metadata file by updating stats and metadata generation options (!N.B. tab separated lines, see below for details). I.e. for ensembl-production-metazoa/meta/105/dmel:

# stats and metadata generation options
#CONF   IGNORE_UNVALID_SOURCE_GFF       1
#CONF   STOP_AFTER_GFF_STATS    NO
#CONF   STOP_AFTER_CONF NO

Meta configuration files

The whole process of creating core database is controlled by the meta configuration file.

Format

Few notations are used.

• Empty lines are ignored.
• One is just a plain text line of the form (tab-separated)

meta_key \t meta_value

to be loaded as is into core's meta table. I.e.

assembly.provider_name  FlyBase
assembly.provider_url   https://www.flybase.org

• Special technical metadata (options) lines starting with #CONF (no spaces after #) of the form (tab-separated)

#CONF \t CONF_OPTION_NAME \t CONF_OPTION_VALUE

. I.e.

#CONF   ASM_URL ftp://ftp.flybase.net/genomes/Drosophila_melanogaster/dmel_r6.37_FB2020_01
#CONF   FNA_FILE        fasta/dmel-all-chromosome-r6.37.fasta.gz

• Anything else having a # sign is a comment (pay attention to the strain names, etc., as no quotation is implemented). I.e. # CONF is not longer a technical data, and thus ignored.

Further description can be found in the Metaconf options document

Back up and restoration from snapshots

• ${DATA_DIR}/<meta_name>/bup -- to store most recent core backup (usually, created after each stage by backup_relink wrapper)

backup_relink $DBNAME $CMD new_loader $DATA_DIR/bup

every step altering core database is followed (at least should be) by backup_relink further

Restoration from snapshot {#restore}

• To restore from the latest backup just use the generic runner with the restore option (see "Parameters for mz_genenic runner" for more details). I.e.

./ensembl-production-metazoa/scripts/mz_generic.sh ${METACONF_DIR}/dmel restore

• To restore from the earlier dump, specify additional tag_pattern after the restore option, i.e.

./ensembl-production-metazoa/scripts/mz_generic.sh ${METACONF_DIR}/dmel restore core_stats

In this case, the back up file matching the specified tag_pattern will be used. All the back up files that are fresher then the specified one will be droped.

Use ls -lt ${DATA_DIR}/<meta_name>/bup to list the available backup files.

N.B. Don't forget to drop as many ${DATA_DIR}/<meta_name>/done tags as you need (use ls -lt to sort tags by time).
