NAME

       unikmer - Toolkit for nucleic acid k-mer analysis

DESCRIPTION

       unikmer - Toolkit for k-mer with taxonomic information

       unikmer  is  a  toolkit for nucleic acid k-mer analysis, providing functions including set
       operation on k-mers optional with TaxIds but without count information.

       K-mers are either encoded (k<=32) or hashed (arbitrary k) into 'uint64', and serialized in
       binary file with extension '.unik'.

       TaxIds  can be assigned when counting k-mers from genome sequences, and LCA (Lowest Common
       Ancestor) is computed during set opertions including computing  union,  intersection,  set
       difference, unique and repeated k-mers.

       Version: v0.19.0

       Dataset (optional):

              Manipulating k-mers with TaxIds  needs  taxonomy  file  from  e.g.,  NCBI  Taxonomy
              database,  please extract "nodes.dmp", "names.dmp", "delnodes.dmp" and "merged.dmp"
              from          link           below           into           ~/.unikmer/           ,
              ftp://ftp.ncbi.nih.gov/pub/taxonomy/taxdump.tar.gz  ,  or some other directory, and
              later you can refer to using flag --data-dir or environment variable UNIKMER_DB.

              For GTDB, use 'taxonkit create-taxdump' to create NCBI-style taxonomy  dump  files,
              or download from:

              https://github.com/shenwei356/gtdb-taxonomy

              Note  that  TaxIds  are represented using uint32 and stored in 4 or less bytes, all
              TaxIds should be in the range of [1, 4294967295]

   Flags:
       -c, --compact
              write compact binary file with little loss of speed

       --compression-level int
              compression level (default -1)

       --data-dir string
              directory  containing  NCBI  Taxonomy  files,   including   nodes.dmp,   names.dmp,
              merged.dmp and delnodes.dmp (default "/home/nilesh/.unikmer")

       -h, --help
              help for unikmer

       -I, --ignore-taxid
              ignore taxonomy information

       -i, --infile-list string
              file  of input files list (one file per line), if given, they are appended to files
              from cli arguments

       --max-taxid uint32
              for smaller TaxIds, we can use  less  space  to  store  TaxIds.  default  value  is
              1<<32-1, that's enough for NCBI Taxonomy TaxIds (default 4294967295)

       -C, --no-compress
              do not compress binary file (not recommended)

       --nocheck-file
              do not check binary file, when using process substitution or named pipe

       -j, --threads int
              number of CPUs to use (default 4)

       --verbose
              print verbose information
