ISAnalytics 1.11.1 (2023-05-09)

FIXES

• Fixed broken tests with new updates in underlying packages

ISAnalytics 1.9.3 (2023-04-04)

ENHANCES AND REFACTORING

• The package no longer depends on magrittr
• All functionality associated with data.table now it’s completely optional and will be used internally only if the package is available
• Several packages were moved from Imports to Suggests - functions will notify when additional packages are requested for the specific functionality
• All known deprecated or superseded functions from other packages have been removed or substituted

FIXES AND GENERAL UPDATES

• Added a new tag “barcode_mux” in available_tags()
• The function HSC_population_size_estimate() now better supports the computation of estimates from different groups of cell types and tissues at the same time. The tabular output now contains an additional column “Timepoints_included” that specifies how many time points the estimate contains
• Function is_sharing() can now handle better limit cases and has the option of being parallelised provided appropriate packages are available (better performance)

DEPRECATIONS & BREAKING CHANGES

• Functions import_parallel_Vispa2Matrices_auto() and import_parallel_Vispa2Matrices_interactive() are officially defunct and will not be exported anymore starting from the next release cycle
• The argument mode of import_parallel_Vispa2Matrices() no longer accepts INTERACTIVE as a valid option and the interactive mode is considered now defunct, since the usage is very limiting and limited
• The argument association_file of import_parallel_Vispa2Matrices() no longer accepts a string representing a path. Association file import is delegated solely to its dedicated function from now on.
• The function threshold_filter() is deprecated, since its use is rather complicated instead of using standard filtering with dplyr or similar tools

MINOR CHANGES

• default_af_transform() now pads time points based on the maximum number of characters + 1 in the column

ISAnalytics 1.9.2 (2023-01-26)

FIXES AND GENERAL UPDATES

• Fixed dplyr warning in integration_alluvial_plot() internals
• Fixed issue with report of VISPA2 stats - report failed due to minor error in rmd fragment
• Internals of remove_collisions() use again dplyr internally for joining and grouping operations - needed because of performance issues with data.table
• fisher_scatterplot() has 2 new arguments that allow the disabling of highlighting for some genes even if their p-value is under the threshold

ISAnalytics 1.5.4 (2022-04-20)

MAJOR CHANGES

• ISAnalytics has now a new “dynamic vars system” to allow more flexibility on user inputs, view the dedicated vignette with vignette("workflow_start", package="ISAnalytics")
• All package functions were reviewed to work properly with this system

NEW FEATURES

• gene_frequency_fisher() is a new function of the analysis family that allows the computation of Fisher’s exact test p-values on gene frequency - fisher_scatterplot() is the associated plotting function
• top_targeted_genes() is a new function of the analysis family that produces the top n targeted genes based on the number of IS
• NGSdataExplorer() is a newly implemented Shiny interface that allows the exploration and plotting of data

ISAnalytics 1.3.2 (2021-06-28)

FIXES

• Corrected issues in man pages

• is_sharing computes the sharing of IS between groups
• sharing_heatmap allows visualization of sharing data through heatmaps
• integration_alluvial_plot allows visualization of integration sites distribution in groups over time.
• top_abund_tableGrob can be used in combination with the previous function or by itself to obtain a summary of top abundant integrations as an R graphic (tableGrob) object that can be combined with plots.

MINOR UPDATES

• Added more default stats functions to default_stats
• Added optional automatic conversion of time points in months and years when importing association file
• Minor fixes in generate_Vispa2_launch_AF

ISAnalytics 1.1.11 (2021-05-11)

NEW FUNCTIONALITY

• HSC_population_size_estimate and HSC_population_plot allow estimates on hematopoietic stem cell population size
• Importing of Vispa2 stats per pool now has a dedicated function, import_Vispa2_stats
• outlier_filter and outliers_by_pool_fragments offer a mean to filter poorly represented samples based on custom outliers tests

VISIBLE USER CHANGES

• The argument import_stats of aggregate_metadata is officially deprecated in favor of import_Vispa2_stats
• aggregate_metadata is now a lot more flexible on what operations can be performed on columns via the new argument aggregating_functions
• import_association_file allows directly for the import of Vispa2 stats and converts time points to months and years where not already present
• File system alignment of import_association_file now produces 3 separate columns for paths
• separate_quant_matrices and comparison_matrix now do not require mandatory columns other than the quantifications - this allows for separation or joining also for aggregated matrices

FIXES

• Fixed a minor issue in CIS_volcano_plot that caused duplication of some labels if highlighted genes were provided in input

ISAnalytics 1.1.10 (2021-04-08)

FIXES

• Fixed issue in compute_near_integrations: when provided recalibration map export path as a folder now the function works correctly and produces an automatically generated file name
• Fixed issue in aggregate_metadata: now paths to folder that contains Vispa2 stats is looked up correctly. Also, VISPA2 stats columns are aggregated if found in the input data frame independently from the parameter import_stats.

IMPROVEMENTS

• compute_abundance can now take as input aggregated matrices and has additional parameters to offer more flexibility to the user. Major updates and improvements also on documentation and reproducible examples.
• Major improvements in function import_single_Vispa2Matrix: import is now preferentially carried out using data.table::fread greatly speeding up the process - where not possible readr::read_delim is used instead
• Major improvements in function import_association_file: greatly improved parsing precision (each column has a dedicated type), import report now signals parsing problems and their location and signals also problems in parsing dates. Report also includes potential problems in column names and signals missing data in important columns. Added also the possibility to give various file formats in input including *.xls(x) formats.
• Function top_integrations can now take additional parameters to compute top n genes for each specified group
• Removed faceting parameters in CIS_volcano_plot due to poor precision (easier to add faceting manually) and added parameters to return the data frame that generated the plot as an additional result. Also, it is now possible to specify a vector of gene names to highlight even if they’re not above the annotation threshold.

MINOR

• ISAnalytics website has improved graphic theme and has an additional button on the right that leads to the devel (or release) version of the website
• Updated vignettes

FOR DEVS ONLY

• Complete rework of test suite to be compliant to testthat v.3

FIXES
