obisort: Sorts sequence records according to the value of a given attribute¶
obisort sorts sequence records according to the value of a given attribute, which can be either numeric or alphanumeric.
obisort specific options¶
- 
-k<KEY>,--key=<KEY>¶ - Attribute used to sort the sequence records.
Example:
> obisort -k count seq1.fasta > seq2.fasta
Sorts the sequence records of file
seq1.fastaaccording to their count (numeric order) and prints the results in theseq2.fastafile. 
- 
-r,--reverse¶ - Sorts in reverse order.
Example:
> obisort -r -k count seq1.fastq > seq2.fastq
Sorts the sequence records of file
seq1.fastaaccording to their count (reverse numeric order) and prints the results in theseq2.fastafile. 
Options to specify input format¶
Restrict the analysis to a sub-part of the input file¶
- 
--skip<N>¶ The N first sequence records of the file are discarded from the analysis and not reported to the output file
- 
--only<N>¶ Only the N next sequence records of the file are analyzed. The following sequences in the file are neither analyzed, neither reported to the output file. This option can be used conjointly with the –skip option.
