Release notes

Version 3.8.0 (2026-07-10)

  • Added in-air oxygen optode gain calibration: RSKinairO2calibration and the routines.inairO2calibration routine add a corrected dissolved-O2 saturation and/or concentration channel.

  • Barometric correction of sea pressure: RSKimportbarometer loads an atmospheric-pressure series (from a barometer .rsk, a .csv, a measured pressure channel of the same RSK, or an Nx2 [utc_ms, dbar] matrix) and attaches it to the marine RSK; RSKderiveseapressure (called without patm) then subtracts it for a corrected sea pressure, and RSKremovebarometer reverts to the constant atmospheric pressure. Marine samples outside the barometer’s coverage take the nearest reading held constant.

  • RSKopen reads back a previously imported barometer; RSK2RSKFULL (v3) and RSK2RSK (v2) persist it on export.

  • Eligible files are schema 3.2.0+, or 2.18.2/2.19.0 with dbType full/live/EPdesktop.

  • RSKopen/RSKreaddata now handle files with no deployment/epoch metadata by falling back to a wide time window; RSKderiveseapressure falls back to the default atmospheric pressure when there is no ATMOSPHERE parameter; also fixed readpowertable erroring on an empty firmwareType.

  • User-facing output (logs, warnings/errors, plot titles, export filenames) now always uses the schedule label, never the numeric schedule id.

  • Fixed a channel/data column index shift when a channel is hidden on pre-3.0.0 schema files.

  • Restyled the Sphinx documentation.

Version 3.7.0 (2026-06-08)

  • Support for 3.0.0 and 3.2.0 schema RSK files: the new metadata/data table structure, multi-schedule data stored per schedule in RSK.dataArrays, and a label-based schedule API (functions take a schedule label such as 's.CTD' rather than a numeric ID)

  • Multi-schedule support across the toolbox: read, RSKderive*, post-processing, region/profile, export, and plot/view functions all operate per schedule

  • Cross-schedule fill (getrefdataset/filldataset) so derivations whose inputs live on different schedules (e.g. dissolved O2 saturation, where O2 and temperature are on different schedules) are populated instead of NaN

  • Stricter derive-dependency policy (aligned with pyRSKtools): a required channel that exists but is entirely NaN now raises instead of producing NaN; an absent sea pressure channel is still auto-derived (with a warning); salinity is never auto-derived. Added the channelallnan helper (true if a channel is entirely NaN, or absent, across all schedules)

  • RSKderivesalinity and RSKderiveseapressure now return only the RSK structure; RSKderiveseapressure accepts a per-schedule atmospheric pressure (a cell array with one scalar or vector per schedule)

  • Added the +routines package of standalone, array-in / array-out processing functions, each in its own versioned file so it can be lifted into another project unchanged

  • Added routines.correcttempADCcal (removes the periodic once-per-minute A2D self-calibration outliers from a temperature series) and its post-processor RSKcorrecttempADCcal (adds a “Temperature Corrected” channel inheriting the source temperature channel’s type and units, and on files with no confirmable self-cal signature returns the series unchanged with no error, rather than fabricating a correction)

  • Added RSK2RSKFULL for exporting full 3.0.0+ schema RSK files (renamed from RSK2RSKV300), with channel/data alignment fixes; fixed CSV2RSK and RSK2RSK and added scheduleNumber

  • Fixed RSK2RSK leaving the mode-specific schedule table empty, which made Ruskin throw a Schedule-to-ContinuousSchedule cast error when opening an exported file; it now writes the full schedules table plus the matching mode table (continuous/burst/wave/tide/average/directional)

  • RSK2RSK now writes channels.label (set to longName), so a derived channel that inherited its source’s shortName (e.g. “Temperature Corrected”) shows its own name in Ruskin instead of the source channel’s name

  • Unified the channel naming convention with pyRSKtools; temperature channels are renamed to descriptive names by sensor type (e.g. conductivity cell temperature, pressure gauge temperature)

  • Added a QuickStart/Demo.m mirroring the pyRSKtools demo notebook, runnable end-to-end in MATLAB

  • Added Sphinx documentation and unified the help-text formatting across the toolbox

  • User-facing messages now refer to schedule labels rather than numeric schedule IDs

  • Extended RSKwarning/RSKerror to accept printf-style arguments

  • Aligned plot parameters with pyRSKtools and fixed a plotting failure when a threshold option is empty

  • Fixed channel order when hidden channels are present, and fixed hidden channels appearing in RSK.channels

  • Fixed RSKderiveO2 appending a redundant O2 channel; RSKcalculateCTlag now requires conductivity and temperature in a single schedule

  • Detect the burst-data table name (dataWave) on v3.2.0 files; fixed the downsample query table name and a tstamp read error on the new schema

  • Fixed RSKopen reading the v3 channel ranging table on the wrong join key (joining instrumentChannel to channel by ic.id instead of ic.channelId), which mismatched the per-channel range metadata in RSK.ranging on 3.0.0/3.2.0 files

  • Fixed default-schedule resolution (resolvedefaultschedule/resolvedefaultschedulect) erroring on multi-schedule files, where a global channel index could overrun a schedule’s narrower per-schedule values matrix; it is now bounds-checked before counting valid samples

  • Fixed RSKderiveseapressure erroring on a multi-schedule file with no pressure channel (the no-pressure sentinel reached the cross-schedule fetch as an invalid column index)

  • Normalised prose to British English, fixed typos, and corrected docstring/code mismatches found in an audit
