class Monochrom(Source):
"""
This class will leverage the GENO ontology and modeling patterns to build
an ontology of chromosomes for any species. These classes represent major
structural pieces of Chromosomes which are often universally referenced,
using physical properties/observations that remain constant over different
genome builds (such as banding patterns and arms). The idea is to create a
scaffold upon which we can hang build-specific chromosomal coordinates,
and reason across them.
In general, this will take the cytogenic bands files from UCSC, and create
missing grouping classes, in order to build the partonomy from a very
specific chromosomal band up through the chromosome itself and enable
overlap and containment queries. We use RO:subsequence_of as our
relationship between nested chromosomal parts. For example,
13q21.31 ==> 13q21.31, 13q21.3, 13q21, 13q2, 13q, 13
At the moment, this only computes the bands for
Human, Mouse, Zebrafish, and Rat
but will be expanding in the future as needed.
Because this is a universal framework to represent the chromosomal
structure of any species, we must mint identifiers for each chromosome
and part. We differentiate species by first creating a species-specific
genome, then for each species-specific chromosome we include the NCBI taxon
number together with the chromosome number, like:
```<species number>chr<num><band>```. For 13q21.31, this would be
9606chr13q21.31.
We then create triples for a given band like:
<pre>
CHR:9606chr1p36.33 rdf[type] SO:chromosome_band
CHR:9606chr1p36 subsequence_of :9606chr1p36.3
</pre>
where any band in the file is an instance of a chr_band
(or a more specific type), is a subsequence of it's containing region.
We determine the containing regions of the band by parsing the band-string;
since each alphanumeric is a significant "place", we can split it with the
shorter strings being parents of the longer string
Since this is small, and we have not limited other items in our test set to
a small region, we simply use the whole graph (genome)
for testing purposes, and copy the main graph to the test graph.
Since this Dipper class is building an ONTOLOGY,
rather than instance-level data, we must also include domain and range
constraints, and other owl-isms.
TODO: any species by commandline argument
We are currently mapping these to the **CHR idspace**,
but this is NOT YET APPROVED and is subject to change.
