+#TOOL2 abstracts_by_pmids
+#
+#This tool retrieves for all PMIDs in each row of a table the according abstracts and saves them in additional columns.
+#
+#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.
+#
+#Output: Input table with additional columns containing abstracts corresponding to the PMIDs from PubMed.
+#The abstract columns are called "ABSTRACT_1", "ABSTARCT_2" etc.
+#
+# Usage: $ T2_abstracts_by_pmid.R [-h] [-i INPUT] [-o OUTPUT]
+#
+# optional arguments:
+# -h, --help                 show help message
+# -i INPUT, --input INPUT    input file name. add path if file is not in working directory
+# -o OUTPUT, --output OUTPUT output file name. [default "T2_output"]
