Fisheries Science: SAMtool (Stock Assessment Methods Toolkit) In ecology and fisheries, is an R package used for evaluating stock assessments through closed-loop simulation. It supports a variety of assessment models Assessment Models : Includes Delay-Difference models , Surplus Production models (e.g., ), and integrated Age-Structured models (e.g., SCA - Statistical Catch-at-Age Conditioning Models : It provides operating models to inform data-rich fisheries management.

At its core, the most fundamental "model" supported by SAMtools is not an algorithm, but a data structure: the Sequence Alignment/Map (SAM) format and its binary equivalent (BAM). The SAM format acts as a generic nucleotide alignment format designed to be the lingua franca of sequencing data. The "model" here describes how sequencing reads are mapped to a reference genome, storing critical metadata such as alignment scores, mapping quality, and the position of the read.

Traditionally, these models have relied on heuristic and frequentist statistical approaches. For example, the calling model calculates the likelihood of a specific genotype given the observed nucleotide counts at a genomic position. It supports models for diploid and haploid organisms, adjusting for sequencing depth and base quality scores. This statistical modeling is crucial; without a robust mathematical framework to interpret the raw data, the alignment files would remain uninterpretable binary blobs. The support for different ploidy models (diploid, haploid, polyploid) demonstrates the software's adaptability to diverse genetic architectures.
But one question dominates the technical forums: Which models actually work with SAMtool? The answer is more nuanced than a simple list. Here is your comprehensive guide to the architectures, checkpoints, and custom variants supported by the modern SAMtool ecosystem.
Standard parameters are tuned for short reads. You must adjust for the long-read model.
