# genome_updater [](https://app.travis-ci.com/pirovc/genome_updater) [](https://codecov.io/gh/pirovc/genome_updater) [](https://anaconda.org/bioconda/genome_updater)
genome_updater is a bash script that downloads and updates (non-redundant) snapshots of the NCBI Genomes repository (RefSeq/GenBank) [[1](https://ftp.ncbi.nlm.nih.gov/genomes/)] with advanced filters, detailed logs and reports, file integrity checks (MD5), NCBI taxonomy and GTDB [[2](https://gtdb.ecogenomic.org/)] integration and support for parallel [[3](https://doi.org/10.5281/zenodo.1146014)] downloads. genome_updater uses the [assembly_summary.txt](https://ftp.ncbi.nlm.nih.gov/genomes/README_assembly_summary.txt) to retrieve data.
## Quick usage guide
### Download
```bash
wget --quiet --show-progress https://raw.githubusercontent.com/pirovc/genome_updater/master/genome_updater.sh
chmod +x genome_updater.sh
```
### Usage
Downloading archaeal complete genome genomic sequences from RefSeq:
```bash
./genome_updater.sh -o "arc_refseq_cg" -d "refseq" -g "archaea" -l "complete genome" -f "genomic.fna.gz" -t 12
```
Some days later, update the local repository to download newly added files:
```bash
./genome_updater.sh -o "arc_refseq_cg"
```
- `-t` number of downloads in parallel.
- `-k` can be used to perform a dry-run, showing how many files will be downloaded/updated.
## Important parameters
A list of all parameters can be found [here](#genome_updater--h)
### Database/Organism/Taxa
- `-d`: Database/repository
- Options: `refseq`, `genbank`
- `-g`: Whole organims groups
- Options: `archaea`, `bacteria`, `fungi`, `human`, `invertebrate`, `metagenomes`, `other`, `plant`, `protozoa`, `vertebrate_mammalian`, `vertebrate_other`, `viral`
- `-T`: for taxonomy groups with optional negation using the `^` prefix
- Examples: `-T '562'`, `-T '543,^562'`, `-T 'f__Enterobacteriaceae,^s__Escherichia coli'` (with `-M gtdb`)
### Output
- `-o`: Output directory
- Every run generates a snapshot, which can be named using the `-b {snapshot}` option (a timestamp is used by default).
- Downloaded files are stored in a single folder (`{working_dir}/{snapshot}/files/`), but the NCBI FTP file structure can be enforced using the `-N` option (e.g. `{working_dir}/{snapshot}/files/GCF/019/968/985/`).
- `-f`: File types. All file types are listed [here](ttps://ftp.ncbi.nlm.nih.gov/genomes/all/README.txt).
- Example: `-f 'genomic.fna.gz,assembly_report.txt'`.
### Filters
- `-c`: RefSeq category
- Options: `reference genome`, `na`
- `-l`: Assembly level
- Options: `Complete Genome`, `Chromosome`, `Scaffold`, `Contig`
- `-D`/`-E`: Start and end sequence release dates, respectivelly
- Example: `-D 20201231 -E 20251231`
- `-F`: Custom filters for the [assembly_summary.txt](https://ftp.ncbi.nlm.nih.gov/genomes/README_assembly_summary.txt). Can be applied by column (e.g. `$4`) or in the whole file (`$0`). Uses [awk](https://www.gnu.org/software/gawk/manual/gawk.html) conditionals syntax.
- Examples:
- Single: `-F '$14 == "Full"'`
- Multi: `-F '($2 == "PRJNA12377" || $2 == "PRJNA670754") && $4 != "Partial"'`
- Regex: `-F '$8 ~ /bacterium/'`
- Whole-file: `-F '$0 ~ "plasmid"'`
### Taxonomy
- `-A`: limits the number of assemblies for a specific taxonomy rank. [More infos](#Top-assemblies).
- `-A 3` to keep 3 assemblies for each taxonomic leaf.
- `-A 'genus:3'` 3 assemblies for each genus.
- `-M`: taxonomy
- Options: `ncbi` (default), `gtdb`
- The `-M gtdb` option enables GTDB compatibility, keeping only assemblies from the [most recent GTDB release](https://data.gtdb.aau.ecogenomic.org/releases/latest/). The taxonomy filter uses the GTDB format (e.g. `-T 's__Escherichia coli'`).
## Update details
When updating an existing local repository:
- Newly added sequences will be downloaded, creating a new version (`-b`, timestamp by default).
- Removed or old sequences will be retained, but not transferred to the new version.
- Repeated/unchanged files are linked to the new version.
- Arguments can be added to or changed in the update. For example, use the command `./genome_updater.sh -o "arc_refseq_cg" -t 2` to specify a different number of threads, or use the command `./genome_updater.sh -o "arc_refseq_cg" -l ""` to remove the `complete genome` filter.
- The file `history.tsv` will be created in the output folder (`-o`), tracking the versions and arguments used. Please note that boolean flags/arguments are not tracked (e.g. `-m`).
## Installation
### conda/mamba
```bash
conda install -c bioconda genome_updater
```
### direct file download
```bash
wget https://raw.githubusercontent.com/pirovc/genome_updater/master/genome_updater.sh
chmod +x genome_updater.sh
```
- genome_updater is portable and depends on the GNU Core Utilities + few additional tools (`awk` `bc` `find` `join` `md5sum` `parallel` `sed` `tar` `wget`/`curl`) which are commonly available and installed in most distributions.
- If you are not sure if you have them all, just run `genome_updater.sh` and it will tell you if something is missing (otherwise the it will show the help page).
### tests
To test if all genome_updater functions are running properly on your system:
```bash
git clone --recurse-submodules https://github.com/pirovc/genome_updater.git
cd genome_updater
tests/test.sh

```
## Advanced examples
### Download, change and update a repository
```bash
# Dry-run to check files available
./genome_updater.sh -d "refseq" -g "archaea,bacteria" -l "complete genome" -f "genomic.fna.gz" -k
# Download (-o output folder, -t threads, -m checking md5, -u extended assembly accession report)
./genome_updater.sh -d "refseq" -g "archaea,bacteria" -l "complete genome" -f "genomic.fna.gz" -o "arc_bac_refseq_cg" -t 12 -u -m
# Downloading additional .gbff files for the current snapshot (adding genomic.gbff.gz to -f , -i to just add files and not update)
./genome_updater.sh -f "genomic.fna.gz,genomic.gbff.gz" -o "arc_bac_refseq_cg" -i
# Some days later, just check for updates but do not update
./genome_updater.sh -o "arc_bac_refseq_cg" -k
# Perform update
./genome_updater.sh -o "arc_bac_refseq_cg" -u -m
```
### Branch from base version with specific filters
```bash
# Download the complete bacterial refseq
./genome_updater.sh -d "refseq" -g "bacteria" -f "genomic.fna.gz" -o "bac_refseq" -t 12 -m -b "all"
# Branch the main files into two sub-versions (no new files will be downloaded or copied)
./genome_updater.sh -o "bac_refseq" -B "all" -b "complete" -l "complete genome"
./genome_updater.sh -o "bac_refseq" -B "all" -b "reference" -c "reference genome"
```
### Generate sequence reports and URLs
```bash
./genome_updater.sh -d "refseq" -g "fungi" -f "assembly_report.txt" -o "fungi" -t 12 -rpu
```
### Recovering genomic assemblies from an external assembly_summary.txt
```bash
./genome_updater.sh -e /my/path/assembly_summary.txt -f "genomic.fna.gz" -o "recovered_sequences"
```
### Use curl instead of wget, change timeout and retries for download, increase retries
```bash
retries=10 timeout=600 ./genome_updater.sh -g "fungi" -o fungi -t 12 -f "genomic.fna.gz,assembly_report.txt" -L curl -R 10
```
### Use a local taxdump file
```bash
new_taxdump_file="my/local/new_taxdump.tar.gz" ./genome_updater.sh -T 562 -o 562assemblies -t 12
```
- the [new_taxdump](https://ftp.ncbi.nlm.nih.gov/pub/taxonomy/new_taxdump/) is required.
### Alternative download URL
```bash
# NCBI
ncbi_base_url="https://ftp.ncbi.nih.gov/" ./genome_updater.sh -d refseq -g bacteria
# GTDB
gtdb_base_url="https://data.gtdb.ecogenomic.org/releases/latest/" ./genome_updater.sh -d refseq,genbank -g bacteria,archaea
```
## Reports
### assembly accessions
The `-u` parameter activates the output of a list of updated assembly accessions for entries where all files have been successfully downloaded. The file `{timestamp}_assembly_accession.txt` contains the following tab-separated fields:
Added [A] or Removed [R], assembly accession, url
Example:
A GCF_000146045.2 ftp://ftp.ncbi.nlm.nih.gov/genomes/all/GCF/000/146/045/GCF_000146045.2_R64
A GCF_000002515.2 ftp://ftp.ncbi.nlm.nih.gov/genomes/all/GCF/000/002/515/GCF_000002515.2_ASM251v1
R GCF_000091025.4 ftp://ftp.ncbi.nlm.nih.gov/genomes/all/GCF/000/091/025/GCF_000091025.4_ASM9102v4
### sequence accessions
The `-r` parameter activates the output of a list of updated sequence accessions for entries for which all files have been successfully downloaded. This option is only available when the file type contains `assembly_report.txt` . The file `{timestamp}_sequence_accession.txt` contains the following tab-separated fields:
Added [A] or Removed [R], assembly accession, genbank accession, refseq accession, sequence length, taxonomic id
Example:
A GCA_000243255.1 CM001436.1 NZ_CM001436.1 3200946 937775
R GCA_000275865.1 CM001555.1 NZ_CM001555.1 2475100 28892
- Note: if genome_updater breaks or does not finish completely, some files may be missing from the assembly and sequence accession reports.
### URLs (and files)
The `-p` parameter activates the output of a list of failed and successfully downloaded URLs to the files `{timestamp}_url_downloaded.txt` and `{timestamp}_url_failed.txt`. The failed list will only be complete if the command runs to completion without errors or interruptions.
To obtain a list of successfully downloaded files from this report, use the command below to get only new files after updating.
```bash
sed 's#.*/##' {timestamp}_url_list_downloaded.txt
#or
find output_folder/version/files/ -type f
```
## Top assemblies
The `-A` option will select the 'best' assemblies for each taxonomic node (leaf or specific rank) according to four categories (A–D), in order of importance:
A) refseq Category:
1) reference genome
2) na
B) Assembly level:
3) Complete Genome
4) Chromosome
5) Scaffold
6) Contig
C) Relation to type material:
7) assembly from type material
8) assembly from synonym type material
9) assembly from pathotype material
10) assembly designated as neotype
11) assembly designated as reftype
12) ICTV species exemplar
13) ICTV additional isolate
D) Date:
14) Most recent first
