MIC vs volcalc
A side-by-side editorial comparison of MIC and volcalc — release velocity, themes, recent moves, and the top alternatives to consider.
MIC vs volcalc: at a glance
What is MIC?
An antimicrobial testing package cut its genomic half loose to become one thing well.
MIC analyses and validates antimicrobial minimum inhibitory concentration data. Version 2.0.0 removed every genomic function and ported them to a separate package, faLearn, leaving MIC focused on concentration analysis and method validation. The result needs fewer dependencies and no longer requires compilation, which is a meaningful install-time change for a clinical microbiology audience.
What is volcalc?
Rebuilt itself around SMILES and .mol input, then made the chemistry configurable
volcalc estimates the volatility of chemical compounds from their structure, implementing the SIMPOL.1 group-contribution method and the Meredith et al. variant. Version 2.0.0 severed the package from KEGG: calc_vol() takes .mol file paths or SMILES strings directly, is vectorized over multiple compounds, and the group-contribution maths was split into its own simpol1() function. Work since has been chemistry accuracy and configurability — the full set of SIMPOL.1 functional groups, volatility thresholds for clean atmosphere, polluted atmosphere or soil, user-supplied temperature, and a validate option returning NA when structure parsing looks suspect.

An antimicrobial testing package cut its genomic half loose to become one thing well.
◆ Current state
MIC analyses and validates antimicrobial minimum inhibitory concentration data. Version 2.0.0 removed every genomic function and ported them to a separate package, faLearn, leaving MIC focused on concentration analysis and method validation. The result needs fewer dependencies and no longer requires compilation, which is a meaningful install-time change for a clinical microbiology audience.
◆ Where it's heading
The split was announced a release before it happened, with the genomic functions deprecated in 1.2.0 and the destination named. Around that, the substantive work has been on censoring: MIC values are reported with inequality signs, and 1.1.0 then 1.2.0 built out increasingly precise handling of them, separating less-than-or-equal from strictly-less-than and adding tolerance arguments to the comparison and agreement functions. That is the package's real subject matter, and shedding the genomic code is what makes room for it.
◆ Prediction
With the scope settled, expect continued work on validation semantics and on the AMR package interoperability the notes already track. The relationship between MIC and faLearn is the thing to watch, since users of the removed functions now have to install both.

◆ Current state

Work since has been chemistry accuracy and configurability — the full set of SIMPOL.1 functional groups, volatility thresholds for clean atmosphere, polluted atmosphere or soil, user-supplied temperature, and a validate option returning NA when structure parsing looks suspect.
◆ Where it's heading
The arc runs from a script tied to one database toward a general structure-to-volatility tool. Dropping KEGG from the core in 2.0.0, then removing KEGGREST as a dependency entirely in 2.2.0, took the package from volatility for KEGG compounds to volatility for any structure a user can supply. The accompanying manuscript published in 2023, and the changelog since has been careful about coefficient double-counting — amines and amides have each been corrected — which suggests the group definitions are the part under active scrutiny.
◆ Prediction
The smarts_simpol1 dataset added in 2.2.0 documents how functional groups are defined, pointing toward further estimation methods alongside SIMPOL.1 and Meredith; splitting simpol1() out in 2.0.0 was stated to be groundwork for exactly that.
