fasta-subsample <sequence file> <count> [options]
Create a random subset of the sequences in a FASTA formatted file. The random seed is fixed so the same subset will be output in every run of the program unless it is explicitly set.
The name of a file of sequences in FASTA format.
The number of sequences to randomly select for inclusion in the output.
Writes a FASTA formatted file to standard out containing the specified subsample of the original file. If -rest file is specified then any left over sequences are written to file, which is useful for cross-validation.
|-seed||random seed||Seed the random number generator uses to select the sequences.||A seed of 1 is used.|
|-rest||file||Name of the file to send the sequences not selected in the output.||The unselected sequences are just discarded.|
|-off||offset||The offset within each sequence to print.||The sequence is output from its beginning|
|-len||len||The maximum length that printed sequences are constrained to.||The sequence is output until its end.|
