## New Data This is the first human reference dataset available in MapMyCells: **Seattle Alzheimer’s Disease Brain Cell Atlas (SEA-AD) MTG - 10x single nucleus RNAseq** This is a high-resolution transcriptomic cell type atlas from middle temporal gyrus (MTG) from the SEA-AD aged human cohort that spans the spectrum of Alzheimer’s disease. The atlas was created from a single nucleus RNA-sequencing (snRNAseq) dataset of ~2.0 million cells profiled (~1.4 million cells after QC). The atlas is hierarchically organized into nested levels of classification: 3 classes, 24 subclasses, and 139 Supertypes. ## New Algorithms **Deep Generative Mapping** Deep Generative Mapping is a deep generative model algorithm for mapping snRNA-seq data sets and assigning cell type identity, based on Allen Institute-hosted reference taxonomies. Cells mapped with this method are not only assigned an associated cell type, but also associated confidence on mapping, and additional information for visualizing and quantifying the level of agreement. Learn more about this algorithm in: Gabitto MI, Travaglini KJ, et al. Integrated multimodal cell atlas of Alzheimer’s disease. Res Sq [Preprint]. 2023 May 23:rs.3.rs-2921860. doi: 10.21203/rs.3.rs-2921860/v1. PMID: 37292694; PMCID: PMC10246227 **SEA-AD Correlation & Hierarchical Mapping** The Correlation & Hierarchical Mapping algorithms from the first MapMyCells release have been re-trained to now also process human data. Learn more about these algorithms here: [Taxonomies](https://portal.brain-map.org/explore/cell-type-references-and-algorithms) ## New Features **Cite this tool button.** Researchers can now easily cite MapMyCells by using the new “CITE THIS TOOL” button. It can be found at the bottom of the Step 1 section in the user interface and links to [MapMyCells’ RRID entry](https://scicrunch.org/resources/data/record/nlx_144509-1/SCR_024672/resolver?q=MapMyCells&l=MapMyCells&i=rrid:scr_024672). ![MMC_CiteThisTool](https://canada1.discourse-cdn.com/flex027/uploads/brainobservatory/original/2X/b/bf4ce8548e35c6a6d7ae77ec87c7b12496ebf3b3.png) **Mapping outputs now in .zip file.** The mapping results package now comes in an easier to use .zip file instead of the prior .tar tarball. This also resolves a set of issues that could results from long file names. **Counts of mapping cells & genes in results table (signed-in experience)** We added a new column to the “Map Results” table that features the counts of mapped cells & genes for each run. These are intended as summary statistics and allows researchers to assess the coverage of the mapping before downloading the results for a deeper analysis. **General UI and dialog polish** We also included several smaller quality-of-life improvements: - Changed link styling to better highlight documentation links in light-mode color scheme. - New confirmation dialog prevents accidental cancellation of an in-progress mapping. - Consistent loading bar fixed to top of page, e.g when deleting a mapping result. - Reduced white space in “Map Results” table (signed-in experience). - Improved text wrapping in “Map Results” table (signed-in experience).

I am enthusiastic about utilizing MapmyCell for exploring the cell types within my research dataset. However, I would appreciate more information about the security measures of uploading my research data to mapp my cells. ---

Hi @KatherineMO, Thank you for your interest in MapMyCells. Please see the response from Elysha Fiabane in this thread: > [@Data privacy. Should all data used in mapmycells be data ok to share publicly?](https://community.brain-map.org/t/data-privacy-should-all-data-used-in-mapmycells-be-data-ok-to-share-publicly/2921/2): > > Hi @abbeygreen, Thank you for your interest in MapMyCells. Internal administrators at the Allen Institute have the technical ability to access any dataset uploaded to MapMyCells. However, we only ever do this when it is necessary for debugging (for example, if a mapping job fails and a user asks us for a deeper explanation than they can get from the returned error logs). We do not aggregate submitted data for any kind of re-training effort, etc, and we will not publish your data publicly. In … If you have further questions, please elaborate on what security aspects you have further questions about and tag @Elysha-AIBS .
