Samtool Supported Models 💯 High Speed

The core of variant calling in SAMtools is the mpileup model. Given a reference genome and aligned reads, it computes:

Mathematically, the likelihood of a genotype $G$ given read data $D$ is approximated as: $$P(D|G) \propto \prod_reads P(read|G, \textbase qual, \textmap qual)$$

SAMtools implements this using a simple, fast forward-backward algorithm, unlike the pair-HMM used in GATK.

Introduction: What is SAMTool?

In the world of mobile device servicing, Samsung stands as a titan. However, its robust security protocols—Knox, Vaultkeeper, and enhanced RMM (Remote Management) locks—make repair, unbricking, and software manipulation challenging for technicians. Enter SAMTool (often stylized as SAM Tool or sam.tool). This third-party software has become an industry favorite for its ability to bypass FRP (Factory Reset Protection), remove Samsung accounts, flash custom binaries, and repair IMEI numbers without requiring a physical JTAG or a complicated box.

But the golden question asked by every technician before purchasing a license is: Which exact models does SAMTool support?

This article provides a comprehensive, up-to-date list of SAMTool supported models, segmented by processor type, Android version, and security patch level.

SAMtool has evolved from a simple inference script into a robust model hub. By supporting everything from the 5MB MobileSAM to the 2.6GB SAM-H via quantization, it democratizes access to state-of-the-art segmentation. However, success depends on matching the model to your hardware constraints.

Before you run samtool predict, verify your model’s architecture. If it’s a standard ViT or Hiera checkpoint from the official SAM family, you are golden. If it’s a research prototype with a custom neck or decoder, you are likely out of luck.

Have a specific model you want to test? Check the official samtool.models.registry to see if your checkpoint hash is listed.

In the context of Meta’s Segment Anything Model (SAM), there are several generations of models designed for different image and video tasks. Current SAM Tool Supported Models

Meta has expanded the original SAM framework into specialized versions for video and 3D reconstruction:

SAM 3.1 & SAM 3: The latest foundation models for real-time video segmentation and object detection. These use the Meta Perception Encoder to achieve higher performance and speed for real-world computer vision tasks.

SAM 2: A unified model for both image and video segmentation. It features a "memory module" that allows it to track objects through video frames even when they are temporarily occluded.

SAM 3D: A suite of models focused on converting 2D images into 3D reconstructions.

SAM 3D Objects: Reconstructs the geometry and texture of physical objects and entire scenes. samtool supported models

SAM 3D Body: Specialized in human body shape and pose estimation from a single image.

Original SAM: The first foundation model for promptable image segmentation, capable of generating masks for any object in an image using points or bounding boxes. Core Technical Features

Promptable Design: Users can interact with these models using points, boxes, or masks to specify which object to segment.

Zero-Shot Generalization: These models are trained on massive datasets (like the SA-1B dataset), allowing them to recognize and segment objects they have never seen before without additional training.

Streaming Architecture: SAM 2 and SAM 3 process video frames sequentially, making them suitable for real-time applications.

Note on SAMtools: If you are instead looking for the bioinformatics toolkit SAMtools, it does not use "models" in the AI sense. It is a suite of utilities for processing sequence alignment files in SAM, BAM, and CRAM formats. It is frequently used alongside BCFtools for variant calling. Introducing Meta Segment Anything Model 2 (SAM 2)

Since "samtool" can refer to different technical domains, this paper overview focuses on the

R package used in fisheries science, which provides a comprehensive suite of "Stock Assessment Methods".

The SAMtool (Stock Assessment Methods toolkit) is an R-based framework designed to bridge data-rich and data-moderate stock assessments within the Management Strategy Evaluation (MSE)

framework. It provides a standardized environment for conditioning operating models, running various assessment models, and implementing model-based management procedures. 1. Core Supported Assessment Models

SAMtool integrates several tiers of assessment complexity, from simple production models to data-rich age-structured models. Surplus Production Models (SP): Includes the (State-Space) and models, which estimate cap F sub cap M cap S cap Y end-sub cap M cap S cap Y using biomass indices and catch data. Statistical Catch-at-Age (SCA): Data-rich models such as (Catch-at-Length), and variants like (Density-Dependent Maturity). Virtual Population Analysis (VPA):

Classic age-structured assessment methods for reconstructing historical population size from catch-at-age. Delay-Difference Models (DD): (Continuous Delay-Difference) and

, which utilize the TMB (Template Model Builder) package for efficient parameter estimation. 2. Conditioning and Diagnostic Tools

Beyond standalone assessments, the toolkit offers models for "scoping" and validating fishery data. Rapid Conditioning Model (RCM): Formerly known as

, this model is used for conditioning operating models in the environment. Model Diagnostics: Includes functions for likelihood profiling ( ), retrospective analysis ( plot.retro ), and residual analysis ( plot_residuals ) to ensure model fit and stability. 3. Management Procedures (MP) The core of variant calling in SAMtools is

provides "Model-based-MP" functions that link assessment outputs directly to Harvest Control Rules (HCRs) HCR_fixedF maintains a constant fishing mortality. Sliding Scale Rules:

adjust fishing effort based on current biomass relative to target benchmarks. Escapement Rules: HCR_escapement for managing stocks with high recruitment variability. Alternative Interpretations

If you were referring to a different "SAM" tool, the supported models vary significantly: SAMtools (Genomics): Supports file formats like SAM, BAM, and CRAM for DNA sequence alignment rather than statistical models. Segment Anything Model (SAM) Tool: Supports AI-driven vision models such as SAM, SAM 2, and SAM 3 for image and video segmentation. or explore the genomic file specifications of the other SAMtools?

is a widely used suite of programs for interacting with high-throughput sequencing data. It does not "support models" in a machine-learning sense, but rather supports specific file formats data structures for sequence alignment: Supported Formats SAM (Sequence Alignment/Map) BAM (binary SAM) Core Capabilities : It provides tools for sorting, merging, indexing

, and retrieving alignment reads. It is often used alongside for variant calling (SNPs and indels).

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. Paper: Understanding the SAM Landscape

The term "SAMtool" serves as a linguistic bridge between two disparate scientific domains: genomic data processing and fisheries management. This paper delineates the supported architectures of both utilities, emphasizing their foundational roles in their respective fields. 1. Genomic Alignment Manipulation (Samtools)

suite remains the industry standard for managing large-scale genomic datasets. Its primary strength lies in its stream-based architecture

, allowing researchers to pipe data between utilities like BCFtools and HTSlib. By supporting the conversion between human-readable SAM and highly compressed BAM/CRAM formats, it enables efficient storage and rapid querying of next-generation sequencing (NGS) data 2. Stock Assessment and Simulation (SAMtool) Conversely, the SAMtool R package focuses on the Management Procedure (MP) framework

. It integrates diverse biological models, ranging from simple catch-based estimators to complex age-structured statistical models . These models are critical for conditioning operating models

that help scientists predict how fish populations respond to different harvesting strategies. Conclusion

The specific functions available depend heavily on the device's chipset and security patch level: SamsTool Online - z3x-team

The exponential growth of genomic data from Illumina, Oxford Nanopore, and PacBio platforms has created a bottleneck not in sequencing, but in primary data processing. The SAM/BAM format (Li et al., 2009) solved the issue of storing aligned reads. However, the real breakthrough was the development of SAMtools, a monolithic yet modular C library and command-line toolset.

A "SAMtools-supported model" refers to any analytical pipeline where SAMtools functions as the critical path executor—specifically for sorting, indexing, filtering, and generating pileup signals. Unlike black-box variant callers, SAMtools-based models offer transparency, low memory footprints, and exceptional speed for specific tasks (e.g., depth-of-coverage calculations).
