Compare
=======

is part of the inStrain module that provides the ability to compare multiple inStrain profiles (created by running inStrain profile).

Note
====

inStrain can only compare inStrain profiles that have been mapped to the same .fasta file

inStrain compare does pairwise comparisons between each input inStrain profile. For each pair, a series of steps are undertaken:

1. All positions in which both IS_profile objects have at least min_cov coverage (5x by default) are identified. This information can be stored in the output by using the flag –store_coverage_overlap, but due to it’s size, it’s not stored by default.


2. Each position identified in step 1 is compared to calculate both conANI and popANI. The way that it compares positions is by testing whether the consensus base in sample 1 is detected at all in sample 2 and vice-versa. Detection of an allele in a sample is based on that allele being above the set -min_freq and -fdr. All detected differences between each pair of samples can be reported if the flag –store_mismatch_locations is set.


3. The coverage overlap and the average nucleotide identity for each scaffold is reported. For details on how this is done.


Inputs
======

Multiple inStrain profiles IS outputs (zip files), all mapped to the same .fasta file


Outputs
=======

1. comparisonsTable.tsv
   
   Summarizes the differences between two inStrain profiles on a scaffold by scaffold level

2. pairwise_SNP_locations.tsv

   Lists the locations of all differences between profiles. Because it’s a big file, this will only be created is you include the flag --store_mismatch_locations in your inStrain compare command.

3. genomeWide_compare.tsv

   A genome-level summary of the differences detected by inStrain compare. Generated by running inStrain genome_wide on the results of inStrain compare

4. strain_clusters.tsv

   The result of clustering the pairwise comparison data provided in genomeWide_compare.tsv to generate strain-level clusters. Performed using hierarchical clustering in the same manner as the program dRep

5. Compare dendrograms (PDF) figure/plot
   
   A dendrogram comparing all samples based on popANI and based on shared_bases.
