Primavera is a Python library to plan and analyze primer-based verification of DNA assemblies, using Sanger sequencing or verification PCR. It implements methods to design and select primers to ensure that the relevant assembly segments will be covered, and it

Usage
-----

**Primer selection**

The following code assumes that a file ``available_primers.fa`` contains the labels and sequences of all available primers in the lab, and that the assemblies to be sequence-verified have annotations indicating the zones that the sequencing should cover and zones where primer annealing should be avoided.

.. code:: python

from primavera import PrimerSelector, Primer, load_record
import os

# LOAD ASSEMBLIES RECORDS AND AVAILABLE PRIMERS
records = [load_record(file_path, linear=False)
for file_path in ['my_record_1.gb', 'my_record_2.gb'...]]
available_primers = Primer.list_from_fasta("example_primers.fa")

# SELECT THE BEST PRIMERS
selector = PrimerSelector(tm_range=(55, 70), size_range=(16, 25))
selected_primers = selector.select_primers(records, available_primers)

# PLOT THE COVERAGE AND WRITE THE PRIMERS IN A SPREADSHEET
selector.plot_coverage(records, selected_primers, 'coverage.pdf')
selector.write_primers_table(selected_primers, 'selected_primers.csv')

The returned ``selected_primers`` contains a list of lists of primers (one list for each construct). The PDF report returned looks like this:
