SB Split to x files

--split_to_x_files, -sxf

Description

Split input file into user-defined number of output files. The number of sequences in each output file is equal to the total number of sequences in the input file divided by the (user-defined) number of output files. Output files are named similar to the input file, followed by a number (if the input file is example.fa, output files are named example_0.fa, example_1.fa etc.). If the number of output files set by the user is greater than the number of records in the input file, the number of output files provided by the user will be overridden by the number of records (in order to avoid the creation of empty output files).

Arguments

file_number ( int )

The number of files to output.
