2 #TOOL2 abstracts_by_pmids
3 #
4 #This tool retrieves for all PMIDs in each row of a table the according abstracts and saves them in additional columns.
5 #
6 #Input: Tab-delimited table with columns containing PMIDs. The names of the PMID columns should start with “PMID”, e.g. “PMID_1”, “PMID_2” etc.
7 #
8 #Output: Input table with additional columns containing abstracts corresponding to the PMIDs from PubMed.
9 #The abstract columns are called "ABSTRACT_1", "ABSTARCT_2" etc.
10 #
11 # Usage: $ T2_abstracts_by_pmid.R [-h] [-i INPUT] [-o OUTPUT]
12 #
13 # optional arguments:
14 # -h, --help show help message
15 # -i INPUT, --input INPUT input file name. add path if file is not in working directory
16 # -o OUTPUT, --output OUTPUT output file name. [default "T2_output"]
