Splits a given data file into N parts such that each part has approximately same number of lines.
split-data.pl [Options] DATA
Type 'split-data.pl --help' for a quick summary of the Options.
DATA should be a file in plain text format such that each line in the DATA file shows a single training example.
Splits the DATA file into N equal parts. If the DATA file has M lines, each part except the last part will have int(M/N) lines while the last part will have all the remaining lines, M - (N-1 * (int(M/N))).
Default N is 10.
Displays the quick summary of options.
Displays the version information.
split-data.pl creates exactly N files in the current directory. If the name of the DATA file is say DATA-file, then the N files will have names as DATA-file1, DATA-file2, DATA-file3,... DATA-fileN. e.g. If the DATA filename is ANC, then the N files created by split-data.pl will have names like ANC1, ANC2, ..., ANCN.
A DATA file containing total M lines is split into N parts such that each part/file contains approximately M/N lines.
Thus, if N = 1, the output file will be exactly same as the given DATA file. If N = M where N = value of --parts and M = #lines in DATA then, each part will have a single line.
