Nicking Hancock

This release incorporates changes to make bowtie2 alignment in CRISPRessoPooled more permissive (44dc9e7), and remove duplicate rows in the Alleles_frequency_table.txt due to reads being in the forward or reverse direction (0e08cd0).

When given a genome file, CRISPRessoPooled aligns reads to the genome using the Bowtie2 aligner. The legacy parameters were somewhat strict. The new parameters reflect the 'default_min_aln_score' parameter in allowing for substantially more indels and mismatches than previous.
The parameter --use_legacy_bowtie2_options_string has been added to use the legacy settings. Otherwise, the bowtie2 alignment settings will be calculated as follows:
--end-to-end - no clipping, match bonus -ma is set to 0
-N 0 number of mismatches allowed in seed alignment
--np 0 where read (or ref have ambiguous character (N)) penalty is 0
--mp 3,2 mismatch penalty - set max mismatch to -3 to coincide with the gap extension penalty (2 is the default min mismatch penalty)
--score-min L,-5,-3*(1-H) For a given homology score, we allow up to (1-H) mismatches (-3) or gap extensions (-3) and one gap open (-5). This score translates to -5 + -3(1-H)L where L is the sequence length

Knockout Lake

Starting in version 2.1.0, insertion quantification has been changed to only include insertions completely contained by the quantification window.
To use the legacy quantification method (i.e. include insertions directly adjacent to the quantification window) please use the parameter --use_legacy_insertion_quantification

This release also includes several updates to:

• prime editing: pegRNA spacer sequences given in the incorrect orientation are no longer tolerated
• HDR: Ambiguous alignments don't contribute to the plot 4g (except when --expand_ambiguous_alignments is provided)
• --fastq_output now also writes alignment scores and alignments for every read

CRISPRessoAggregate Debut

CRISPRessoAggregate can be used to aggregate multiple completed CRISPResso runs.

v2.0.44: Fix plot window cloning from Ref1 to HDR

Improvements in inferring quantification windows across amplicons/alleles.

Axis ticks and other fixes

Add ticks to appropriate plots
Update the function of histograms

• by default 99% of data is shown in plots, now 100% of data is written to data files.
• new parameter --plot_histogram_outlier to plot 100% of data

v2.0.42

Fixed % character in CRISPRessoPooled arg string

WGS and Plotting updates

WGS and Pooled summary figures scale height based on the number of entries so that they are legible in html reports.

WGS parallelization mode bug fixed

Added --fastq-out parameter to report the CRISPResso analysis separately for each read. Note that this should be used with caution. I'm still trying to figure out what information should be reported for each read, and what format it should be in. Open to feedback on this issue!

v2.0.40: Prime editing updates

Prime editing updates - scaffold parameter is now called --prime_editing_pegRNA_scaffold_seq.
Guide names with spaces produce file names with hyphens instead of spaces

v2.0.39

Batch mode supports bam and multiple quantification windows
