chromConverter vs nert: at a glance
What is chromConverter?
The chromatography file-format translator keeps absorbing vendor formats one release at a time
chromConverter reads proprietary chromatography data files into R. Version 0.9.0 adds four input paths — Agilent ACAML markup, Agilent OpenLab .amx method files, preliminary Chromatotec .Chrom support, and plain UTF-8 CSV — while consolidating sample_id and vial into a single sample_position field and introducing a chrom_list class whose print method shows a compact metadata summary instead of dumping every chromatogram.
What is nert?
nert put fourteen TERN datasets behind one dispatcher and called it stable.
nert is an R client for the TERN data API, reaching its first stable release in May 2026 after a year of milestone-tagged development. Version 1.0.0 exposes eleven functions covering fourteen datasets — SMIPS, ASC, AET, eight SLGA soil attributes, Soil Beta Diversity, Canopy Height and Land Surface Phenology — through a single read_tern(dataset_id, ...) dispatcher plus collect_tern_data() for batch extraction across locations and date ranges. Coverage sits at 83% overall with every reader at 100%.

◆ Current state
chromConverter reads proprietary chromatography data files into R. Version 0.9.0 adds four input paths — Agilent ACAML markup, Agilent OpenLab .amx method files, preliminary Chromatotec .Chrom support, and plain UTF-8 CSV — while consolidating sample_id and vial into a single sample_position field and introducing a chrom_list class whose print method shows a compact metadata summary instead of dumping every chromatogram.
◆ Where it's heading
Format coverage is the product, so each release reads as a list of newly readable vendors. The more interesting movement in 0.9.0 is around the data rather than the parsers: consolidating metadata fields, defaulting the rainbow parser to sparse output for long-format MS data, and reordering read_agilent_d to prioritise DAD data over 2D chromatograms. Those are opinions about what users actually want back, and each one breaks existing code.
◆ Prediction
Chromatotec support is described as preliminary, which is the same language that has preceded fuller parser support in this package before.

◆ Current state

Coverage sits at 83% overall with every reader at 100%.
◆ Where it's heading
The release history is unusual in that most of its tags are not releases: Milestone 1, 2 and 4 were pushed within eight minutes of each other in July 2025 purely as grant reporting and audit markers, with no user-facing content. What the 1.0.0 notes emphasise instead is test discipline — 310 deterministic offline tests, snapshot pins on every TERN bucket path and filename template, and mocked COG reads so R CMD check never touches the network. That is a client built on the assumption that the remote API's URL structure will change underneath it.
◆ Prediction
The notes describe pre-CRAN review polish and itemise remaining check NOTEs in cran-comments.md, so the next move is most likely a CRAN submission rather than additional dataset coverage.
