airpg 1.0.2

A package to automatically access the inverted repeats of archived plastid genomes

airpg: Accessing the inverted repeats of archived plastid genomes

A Python package for automatically accessing the inverted repeats of thousands of plastid genomes stored on NCBI Nucleotide

INSTALLATION

To get the most recent stable version of airpg, run:

pip install airpg

Or, alternatively, if you want to get the latest development version of airpg, run:

pip install git+https://github.com/michaelgruenstaeudl/airpg.git

EXAMPLE USAGE

Short survey for the impatient / for testing (runtime ca. 5 hours)

Survey of all plastid genomes of flowering plants submitted to NCBI Nucleotide in 2019 only. Note: The results of this survey are available on Zenodo via DOI 10.5281/zenodo.4335906

Full survey with explanations (runtime ca. 19 hours)

Survey of all plastid genomes of flowering plants submitted to NCBI Nucleotide from start of 2000 until end of October 2020. Note: The results of this survey are available on Zenodo via DOI 10.5281/zenodo.4335906

STEP 1: Querying NCBI Nucleotide for complete plastid genomes given an Entrez search string

TESTFOLDER=./angiosperms_Start2000toEndOct2020
DATE=$(date '+%Y_%m_%d')
ENTREZSTRING='complete genome[TITLE] AND (chloroplast[TITLE] OR plastid[TITLE]) AND 2000/01/01:2020/10/31[PDAT] AND 50000:250000[SLEN] NOT unverified[TITLE] NOT partial[TITLE] AND Magnoliophyta[ORGN]' # complete plastid genomes of all flowering plants between start of 2000 and end of October 2020
RECORDSTABLE=plastome_availability_table_${DATE}.tsv
mkdir -p $TESTFOLDER

# Updating blocklist
if [ ! -f ./airpg_blocklist.txt ]; then
    touch ./airpg_blocklist.txt
    airpg_update_blocklist.py -f ./airpg_blocklist.txt
fi
airpg_update_blocklist.py -f ./airpg_blocklist.txt -m [e-mail] -q "inverted[TITLE] AND repeat[TITLE] AND loss[TITLE]"

airpg_identify.py -q "$ENTREZSTRING" -o $TESTFOLDER/$RECORDSTABLE \
    --blocklist ./airpg_blocklist.txt 1>>$TESTFOLDER/airpg_identify_${DATE}.runlog 2>&1

STEP 2: Retrieving and parsing the genome records identified in step 1, analyzing the position and length of their IR annotations

IRSTATSTABLE=reported_IR_stats_table_${DATE}.tsv
mkdir -p $TESTFOLDER/records_${DATE}
mkdir -p $TESTFOLDER/data_${DATE}

airpg_analyze.py -i $TESTFOLDER/$RECORDSTABLE \
    -r $TESTFOLDER/records_${DATE}/ -d $TESTFOLDER/data_${DATE}/ \
    -m [e-mail] -o $TESTFOLDER/$IRSTATSTABLE 1>>$TESTFOLDER/airpg_analyze_${DATE}.runlog 2>&1
