How To Fix DB2quiva: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu DB2quiva is provided by dazzdb package.

dazzdb is:

To facilitate the multiple phases of the dazzler assembler, all the read data is organized into what is effectively a database of the reads and their meta-information. The design goals for this data base are as follows:

• The database stores the source Pacbio read information in such a way that it can re-create the original input data, thus permitting a user to remove the (effectively redundant) source files. This avoids duplicating the same data, once in the source file and once in the database.
• The data base can be built up incrementally, that is new sequence data can be added to the data base over time.
• The data base flexibly allows one to store any meta-data desired for reads. This is accomplished with the concept of tracks that implementors can add as they need them.
• The data is held in a compressed form equivalent to the .dexta and .dexqv files of the data extraction module. Both the .fasta and .quiva information for each read is held in the data base and can be recreated from it. The .quiva information can be added separately and later on if desired.
• To facilitate job parallel, cluster operation of the phases of the assembler, the database has a concept of a current partitioning in which all the reads that are over a given length and optionally unique to a well, are divided up into blocks containing roughly a given number of bases, except possibly the last block which may have a short count. Often programs can be run on blocks or pairs of blocks and each such job is reasonably well balanced as the blocks are all the same size. One must be careful about changing the partition during an assembly as doing so can void the structural validity of any interim block-based results.

To fix this problem, we can install more using the command below.

sudo apt-get -y install dazzdb

This command might take some time to finish depending on your machine internet connection.

You can also use apt command to install dazzdb.

sudo apt -y install dazzdb

Or if you have aptitude installed you can use the following command.

sudo aptitude install dazzdb
