### subcommands:

-

  Sequence file operation

- count

  Splits sequences files by number of records.

- group

  Splits sequences files by annotation.

- sample

  Randomly samples from unpaired sequences files.

-

  samplepair

-

  Randomly samples from paired-end sequences files.

- sort

  Sorts sequences files by annotation.

- select

### output files:

-

  part\<part\>

-

  reads partitioned by count, where \<part\> is the partition number.

-

  \<field\>-\<value\>

-

  reads partitioned by annotation \<field\> and \<value\>.

-

  under-\<number\>

-

  reads partitioned by numeric threshold where the annotation value is strictly less than the threshold \<number\>.

-

  atleast-\<number\>

-

  reads partitioned by numeric threshold where the annotation value is greater than or equal to the threshold \<number\>.

-

  sorted

-

  reads sorted by annotation value.

-

  sorted-part\<part\>

-

  reads sorted by annotation value and partitioned by count, where \<part\> is the partition number.

-

  sample\<i\>-n\<count\>

-

  randomly sampled reads where \<i\> is a number specifying the sampling instance and \<count\> is the number of sampled reads.
