pdbsplitter - split an FSDB file into multiple files

pdbsplitter splits a single FSDB file into a series of output files. This could be achieved by running dbcol multiple times, but pdbsplitter should be faster when processing many columns.

Example input (myfile.fsdb):

#fsdb -F s col1:l two:a andthree:d
1	key1	42.0
2	key2	123.0
3	key1    90.2

Example command usage

$ pdbsplitter -k col1 -c two andthree -o myfile-split-%s.fsdb myfile.fsdb

Example output

The above command produces two different files, one per each column.

  • myfile-split-two.fsdb:

#fsdb -F t col1 two
1	key1
2	key2
3	key1

  • myfile-split-andthree.fsdb:

#fsdb -F t col1 andthree
1	42.0
2	123.0
3	90.2
