Bio-Logic .mpr files, parsed and plotted — free
What a Bio-Logic .mpr file is, why .mpt exports lose metadata, and how to open/convert Bio-Logic battery data — upload it to Matflow free, or parse it yourself in Python.
Formats: .mpr (binary), .mpt / .txt (text export), .mbi (settings) · For: Battery & electrochemistry labs (EC-Lab)
What the format actually is
Where the data hides, and what a naive parser loses.
Bio-Logic cyclers and potentiostats controlled by EC-Lab write native .mpr files: a binary container holding the data blocks (cycle, time, Ewe, I, capacity…), the technique settings, and instrument metadata for every channel.
The .mpt "export as text" option produces a tab-separated dump that spreadsheets can open — but it silently depends on the EC-Lab locale and version, and the header block (line count varies) trips naive CSV loaders.
Technique changes mid-run (e.g. GEIS inserted between GCPL blocks) split the file into Ns mod-safe blocks with independently resetting time columns — the single most common source of corrupted capacity-per-cycle math.
Vendor quirks that break naive parsers
Each of these has produced a silently wrong number in a real workflow.
Do it yourself in Python
We would rather you succeed with or without us. The open-source path:
What happens if you use Matflow
The parser is only step one — the value is the review and the provenance that follow.
Upload on the Ingestion page
Excel, CSV, PDF, SDS images and instrument files are parsed into evidence-tagged rows — the original file is retained as provenance.
Review before promotion
Column roles and types are proposed for a reason; correcting a mislabeled column here is the highest-leverage five minutes in the workflow.
Promote to a governed dataset
The accepted rows become a versioned dataset any stage can use — every row keeps its source and extraction status.
Docs: ingestion & extraction · column roles · instrument parsers
Stop parsing by hand
Upload your .mpr file to Matflow and it lands as a governed, validated dataset — original file preserved as provenance, every column documented. Free tier, no card.
Other formats we parse
This guide covers one of 10 instrument formats.
