Aboutpysraweb (/paɪ ˌɛs ɑːr eɪ wɛb/) is a web app for fast exploration of datasets from the Sequence Read Archive and Gene Expression Omnibus featuring consolidated tabular views of experiment- and sample-level metadata, substantially reducing navigation overhead and enabling faster exploration and comparison of studies.Frequently Asked Questions
Where does pysraweb fetch its datasets from?We maintain a local mirror of all publicly available datasets on NCBI's FTP servers. This includes all SRA datasets and GEO datasets. We do not own or modify the original data.
Does pysraweb download sequencing data?No. pysraweb only indexes and serves metadata. It does not download or host raw sequencing files such as FASTQ or BAM.
How is pysraweb different from browsing NCBI directly?pysraweb provides unified SRA and GEO metadata, relevance-ranked search, and consolidated tabular views, eliminating multi-page navigation and reducing discovery time.
Is pysraweb suitable for large-scale searches?Yes. The backend is optimized for low-latency queries over millions of records, enabling fast filtering and comparison across studies.
Who is pysraweb intended for?pysraweb is designed for researchers who frequently explore public sequencing metadata and want faster, more structured discovery workflows.
