An Artificial Intelligence-based Pipeline for Drosophila Behavioral Analysis

This is the last lesson in Part 1 of Introductory R for Novices: Getting Started with R. This lesson will focus exclusively on working with data frames. Attendees will learn how to examine, summarize, and access data in data frames.  

This class will introduce beginners or those looking for a refresher to Jupyter Lab, a platform used to organize code and analysis steps in one place. Jupyter Lab can be easily installed or run in a web browser, and supports several languages such as R and Python. It provides a way to keep track of all steps in an analysis and a place for collaboration. This class will not be hands-on and is a demo only. Experience using or installation onto personal computer of Jupyter Lab is not needed to attend. This is for NIH audience only.

The programming language R is ideal for biomedical researchers as it has packages that facilitate Next Generation Sequencing (NGS) data analysis. For example, bulk RNA sequencing differential expression analysis can be performed with DESeq2 and Seurat is used for analyzing single cell RNA sequencing data. When programming, scientists are encouraged to keep track of versions using tools such as Git (https://git-scm.com). Git is a software that saves the history of code, which enables scientists to track and revert changes. This Coding Club will introduce participants to versioning using Git inside of R Studio, a graphical interface for working with R. Essential steps in versioning code such as setting up Git in R Studio, tracking code history, reverting to previous versions, and sharing code on GitHub will be covered. After this class, participants will appreciate the convenience of versioning using Git within R Studio and start to apply materials learned to track changes in their own R scripts. This class is a demo and not hands-on. Attendance is restricted to NIH staff.

This is an introductory level training.

Speaker will: 

• Address how robust AI models in digital pathology are limited not only due to the scarcity of large-scale, annotated data sets but also due to the lack of clear framework for clinical translation. • exemplify a deep learning model that can generate synthetic, but plausible, histological stains from unstained tissue.
• Highlight how NIH exploratory grants (e.g., NIH R21) have made it possible for a feasible technology to become a clinically validated, risk-probability tool (i.e., prognostic model)
• Give perspective on both emerging challenges and standards for validating and approving these complex, AI-enabled medical devices intended for clinical use.

The ability to measure gene expression levels for individual cells (vs. pools of cells) and with spatial resolution is crucial to address many important biological and medical questions, such as the study of stem cell differentiation, the discovery of cellular subtypes in the brain, and cancer diagnosis and treatment. Single-cell transcriptome sequencing (RNA-Seq) allows the high-throughput measurement of gene expression levels for entire genomes at the resolution of single cells. Spatially-resolved transcriptomics further allows the measurement of gene expression levels along with the location of the RNA molecules within a tissue. Transcriptomics exemplifies the range of issues one encounters in a data science workflow, where the data are complex in a variety of ways, questions are not always clearly formulated, there are multiple analysis steps, and drawing on rigorous statistical principles and methods is essential to derive meaningful and reliable biological results. 

In this talk, Dr. Dudoit will provide a survey of statistical questions related to the analysis of single-cell transcriptome sequencing data to investigate the differentiation of stem cells in the brain, including, exploratory data analysis, expression quantitation, cluster analysis, and the inference of cellular lineages. She will also address differential expression analysis in spatial transcriptomics.

Artificial Evolution with Artificial Intelligence

The Genomic Data Commons is releasing a new Correlation Plot Tool which provides a framework for correlating GDC molecular information (mutation, CNV, gene expression) with clinical and survival data. Using quick access features, researchers can compare mutation or CNV status of a gene with a clinical variable or survival, CNV and mutation for given genes, a gene's CNV with its expression, and gene expression level with survival. The tool assists in identifying statistically meaningful correlations between genomic variants and clinical phenotypes to uncover patterns that assist in enabling diagnostic and treatment discoveries. Join us for an overview and demonstration of the GDC Correlation Plot Tool, and associated data supporting correlative analysis.
