Build a Biopython Multiple Sequence Alignment Quality Scorer with Qdrant

Align homologous gene transcripts downloaded from public repositories and calculate pairwise distance matrices. Vectorize alignment features into Qdrant to detect anomalous outlier sequences.

Computational Biologist

Load homologous FASTA transcripts using Biopython SeqIO.

Compute gap frequencies and positional identity matrices across sequence collections.

Vectorize alignment summary profiles and index them in a local Qdrant collection.

Identify distance outliers and output quality warnings for human curator verification.

Streamlit app with interactive distance plots and outlier inspection tables.

Use Biopython test suite FASTA samples and public viral or eukaryotic homologous transcript sets. Starter examples below are synthetic. They are not downloaded records.

Biopython Employs Biopython's sequence analysis data structures to parse FASTA alignments and compute residue statistics.

qdrant, biopython, streamlit. Qdrant provides low-latency vector similarity search to cluster alignment score vectors and find outliers. Small local embedding model or tabular feature projector for alignment metric indexing.

Submit runnable source, pinned dependencies, setup commands, a working interface, example outputs, and a recorded end-to-end demo. Include tests and an action log.

Parses multi-sequence FASTA files accurately using Biopython.

Calculates positional identity and indexes metric vectors into Qdrant.

Flags sequences with high gap penalties or divergent residue scores.

Standard sequence quality profiling tool operating exclusively on open synthetic or public FASTA data. Use mock external writes. Require human review before any real deployment.
