Hypermutator_QTL

Python functions and jupyter notebooks used in QTL analysis of Cryptococcus neoformans hypermutator phenotype in Priest et al. 2021

Dependencies

Python (anaconda) v 3.7.3

  • Used for analysis and visualization

BWA v 0.7.12-r1039

  • Used to align FASTQ file to an XL280 reference genome

Samtools v 1.9

  • Used to generate and filter SAM and BAM files

Freebayes v 1.2.0 haplotype caller

  • Used to detect genetic variants segregating in the mapping population

Bamaddrg

  • Used to add read group information to BAM

Description of notebooks and order of analysis pipeline:

FASTQ_alignment_and_variant_calling

  • A notebook that constructs bash calls for aligning paired-end reads with BWA, SAM to BAM conversion, adding readgroups, and calling freebayes for variant detection

hypermutatorqtl.py

  • A library of dataframes, lists, variables, and functions used across notebooks.

Phenotype_preprocess

  • Transforms and addjusts labels and scles of hypermutator phenotype data.

Genetic_variant_filtering

  • Filters the variant call files across chromosomes and generates supplementary Figure S14 in Priest et al.

Genotype_postprocess

  • Reformats genotpe data and sample names for use in QTL mapping.

Make_chromosome_map

  • Merges chromosome variant data and data from the reference genome to construct a map associated chromosome names and numbers (as well as other data).

Supplementary_Figure_S5

  • Plots the haplotypes across chromosome 3 and 11, generating supplementary Figure S5 in Priest et al.

snpeffect

  • For the QTL regions on chromosome 3 and 11, predicts the changes in amino acid sequnces for genes within these QTL.

QTL_analysis

  • Codnducts QTL analysis of hyptermutator phenotype and genotypes in Bt65 x H99 F1 progeny, generating upper panel of Figure 2 and Supplementary Figure S4 as seen in Priest et al.

Supplementary_Figure_S13

  • For each sampled progeny sequenced from the Bt65 x H99 cross, constructs diagnostic plots of allele, read-depth, allelic read-depth across chromosomes. The plot for progney P25 was used as Supplementary Figure S13 in Priest et al.

ZNF3_visulization

  • Plots the gene model, variants, and amino acids for CNAG_02700 used in middle panel of Figure 2 in Priest et al.

LongCOA_visulization

  • Plots the gene model, variants, and amino acids for CNAG_01836 used in upper panel of Supplementary Figure S7 in Priest et al.
