Benchmarking framework for 3D histology
We developed a benchmarking framework to evaluate the accuracy of several free and commercial 3D reconstruction methods using two whole slide image datasets. The results provide a solid basis for further development and application of 3D histology algorithms and indicate that methods capable of compensating for local tissue deformation are superior to simpler approaches.

Pomo – Plotting Omics analysis results for Multiple Organisms
An interactive web-based application to visually explore omics data analysis results and associations in circular, network and grid views. POMO has built-in references for human, mouse, nematode, fly, yeast, zebrafish, rice, tomato, Arabidopsis, and Escherichia coli. In addition, POMO provides custom options that allow integrated plotting of unsupported strains or closely related species associations, such as human and mouse orthologs or two yeast wild types, studied together within a single analysis.

Pypette – Pythonic utilities for the analysis of high throughput sequencing data
Pypette is a collection of command line utilities and libraries for analyzing biological data. Current functionality includes: Gene expression quantification, copy number analysis, mutation and SNP analysis, chromosomal rearrangement analysis, FASTA, VCF and SAM file manipulation and other miscellaneous functionality. Available at https://github.com/annalam/pypette.
Segmentum: a tool for copy number analysis of cancer genome
Segmentum is a tool for the identification of CNAs and copy-neutral loss of heterozygosity (LOH) in tumor samples using whole-genome sequencing data. Segmentum segments the genome by analyzing the read-depth and B-allele fraction profiles using a double sliding window method. It requires a matched normal sample to correct for biases and to discriminate somatic from germline events. Segmentum, written in the Python programming language, is fast and performs segmentation of a whole genome in less than two minutes. Published in BMC Bioinformatics 18: 215, 2017.

Breakfast – a software for detecting genomic structural variants from DNA sequencing data
Breakfast is a software for detecting genomic structural variants from DNA sequencing data. Its features include: Identifies structural variants based on breakpoint-overlapping reads, extremely fast, analyzes ~40 million reads per minute per CPU core, reports the full sequence of all breakpoint supporting reads, and shows mismatched bases. It identifies PCR/optical duplicates and does not count them as independent sources of evidence, can be run on sorted or unsorted BAM files, or can read BAM input from a pipe, uses pre-existing Bowtie indexes to speed up alignment (does not require its own index), and provides tools for filtering out rearrangements that are present in control samples. Breakfast has been used in a number of publications, most recently in TCGA PanCanAtlas Fusion analysis. Available at https://github.com/annalam/breakfast.
