read_composites and read_composite_info to read and parse metadata in inForm composite images.2021-08-03
Misc: - Update dependencies to modern versions - Fix for bug in readr 2.0.0
2021-06-01
Changes to read_cell_seg_data: - Add a col_select parameter to support reading only selected fields, with a 'phenoptrReports' option to read only fields needed by phenoptrReports. - Use vroom::vroom() instead of readr::read_tsv for speed and support of col_select. - For an export file containing all inForm fields, read_cell_seg_data(csd_path, col_select='phenoptrReports') can be 4-5x faster and use 75% less memory for the results, compared to the previous version.
Spatial distribution report: - Fix report generation to work when paths contain spaces.
Misc: - Fix select_rows to always return FALSE instead of NA. - Update to work with CRAN release of tiff 0.1-8 - Update to work with (and require) spatstat 2.0.0 - Require R 4.0.0 or greater for compatibility with latest rtree

phenoptrReports to avoid installation pain. phenoptrReports is still needed to build the vignettes and to run a few of the examples.parse_phenotypes and validate_phenotype_definitions support expressions in phenotype definitions.2019-05-31
Bug fixes: - Fix density_bands to work with cell seg data in microns with slide origin (#10).
2019-05-10
New feature (and breaking change): - The nearest neighbor functions compute_all_nearest_distance and find_nearest_distance now create columns containing the Cell ID of the nearest cell, as well as the columns with the actual distance. This column can be used to find the locations of nearest cells and to find mutual nearest neighbors. The “Computing inter-cell distances” tutorial shows some uses of this data.
Bug fixes: - read_cell_seg_data recognizes and correctly reads inForm data which uses comma as the decimal separator (#8). - Fix SpatialDistributionReport to work with more than 8 phenotypes (#6). - count_touching_cells ignores phenotype pairs of self to self with a warning because the touching algorithm does not handle this case (#7).

Failed with error: ‘there is no package called ‘rtree’’ message that requireNamespace('rtree') generates (#5).2019-04-12
New features: - Add fast implementation of count_within_many and count_within_batch using akoyabio/rtree package. - Add fast count_within_detail to give per-cell counts.
Bug fixes: - Fix get_field_info to work with the standard (CRAN) tiff package. - count_within and related functions return NA for within_mean when there are no from cells (rather than a mean of 0). - Update spatial_distribution_report vignette and example to use phenoptrExamples, which contains the required component data file (#3). - Fix problem in count_touching_cells when there is exactly one touching cell pair (#4)
