# Introduction | ||
|
||
Surveillance and outbreak analysis of pathogens has been operationalized by multiple public health laboratories around | ||
the world using gene-by-gene approaches. Gene by gene comparisons can be considered the next iteration of multi-locus seuence typing | ||
(MLST) due to the compression of large amounts of sequence information into a set of integer allele identifiers according to a | ||
defined schema. There are a variety of software approaches available to call allele profiles from schemes such as | ||
[chewBBACA](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5885018/). Additionally there are tools available which can calculate | ||
a distant matrix using the standardized allele profile format of ['name', 'locus_1','locus_2'...'locus_n'] in the form of | ||
[GrapeTree](https://github.com/achtman-lab/GrapeTree). However, this method is not tolerant of non-integer data in loci columns and | ||
one of the strengths of chewBBACA is that it will provide additional information in columns in the case of partial matches etc. | ||
Furthermore, there is interest in utilizing hashing of allele sequences for deterministic labelling of alleles without the need | ||
for a centralized allele nomenclature service. Additionally, GrapeTree does not provide functionality for querying samples against | ||
a database of samples. Furthermore, the memory requirements of GrapeTree grow significantly with the number of samples being compared | ||
as the distance matrix is held in memory. As datasets grow, using text based formats such as CSV, TSV represent significant amounts of runtime in terms | ||
of reading, parsing and writing. New formats such as [parquet](https://parquet.apache.org/) support compression and are optimized for | ||
efficiency of storage and retrieval of data. | ||
<br><br> | ||
To address needs of users within our team we have designed an integrated solution for calculating distance matricies and querying of genetically | ||
similar samples within a defined threshold to support outbreak and surveillance activities. We provide the flexibility to have standard text | ||
based outputs as well as parquet. It is implemented in pure python and currently is only available in a single threaded version but later | ||
refinements may include the support for multiprocessing. To facilitate integration of the tool into larger workflows it will also be implemented | ||
as a nextflow workflow. | ||

### Compatibility | ||
|
||
All required packages are listed in the setup.py. The package does require [Numba](https://numba.pydata.org/) to JIT compile certain functions, if any issues during installation are encountered please make an issue on the repository. | ||

## Usage | ||
|
||
### Command Line Options | ||
### **Distance matrix calculation** | ||
|
||
The default behaviour of profile dists is to construct a pairwise distance matrix with the columns representing the | ||
reference sequences and rows representing the query sequences. For clustering analysis, you can construct a symmertic/square | ||
distance matrix by supplying the same profile as reference and query. | ||
|
||
``` | ||
profile_dists --query samples.profile --ref samples.profile --outdir results | ||
``` | ||
|
||
### Fast Matching | ||
|
||
Profile dists also supports querying of a set of sample profiles against a reference database and reporting that as either a | ||
matrix or three column table of [ query_id, reference_id, dist ] | ||
|
||
``` | ||
profile_dists --query queries.profile --ref reference.profile --outdir results --match_threshold 10 | ||
``` | ||
|
||
## Configuration and Settings | ||
|
||
If you run ``profile_dists --help``, you should see the following usage statement describing each parameter `profile_dists` accepts: | ||

|
||
Profile dists also suports querying of a set of sample profiles against a reference database and reporting that as either a | ||
matrix or three column table of [ query_id, reference_id, dist ] | ||
Profile dists supports several different formats as input: | ||
