Someone shared FlowProof results with you. Load the run manifest they sent, then choose your copies of the output files. Each file is hashed with SHA-256 in this browser and compared with the checksum recorded when the run finished. No account needed, and nothing leaves your machine.
A match shows your file is byte-identical to the one the run produced, as recorded in this manifest. The manifest is not cryptographically signed, so get it from the person who ran the analysis. A match does not show that the results are scientifically correct, and FlowProof is for research reproducibility only, not clinical or diagnostic use.
