How To Fix mmmulti: command not found in Ubuntu / Debian / Kali Linux / Raspbian
In Ubuntu mmmulti is provided by mmmulti package.
mmmulti is:
This implements a memory backed multimap intended for use where:
- your keys are integers, or can be mapped to dense range of integers,
- the memory mapped file is on fast storage, like an SSD (although this is not a requirement),
- you have arbitrary values of fixed size (e.g. structs, other POD types) that can be sorted,
- you don’t need dynamic updates of the table,
- and you are likely to run out of memory of you use a traditional map or hash table,
- but you can handle approximately 1 bit per record in RAM.
These may seem to be very specific, but many problems can be mapped into a dense integer set. mmmulti::map developed first as a data structure to support seqwish, which uses it to generate precise variation graphs from pairwise alignments between collections of sequences. As this multimap forms a key data processing kernel in the algorithm, it can scale to extremely large problem sizes, limited only by available disk space. Although performance is much slower than an in-memory structure, it is virtually guaranteed to be able to complete the compute.
To fix this problem, we can install more using the command below.
sudo apt-get -y install mmmulti
This command might take some time to finish depending on your machine internet connection.
You can also use apt command to install mmmulti.
sudo apt -y install mmmulti
Or if you have aptitude installed you can use the following command.
sudo aptitude install mmmulti
