In gene therapy, stem cells are modified using viral vectors to deliver the therapeutic transgene and replace functional properties since the genetic modification is stable and inherited in all cell progeny. The retrieval and mapping of the sequences flanking the virus-host DNA junctions allows the identification of insertion sites (IS), essential for monitoring the evolution of genetically modified cells in vivo. A comprehensive toolkit for the analysis of IS is required to foster clonal trackign studies and supporting the assessment of safety and long term efficacy in vivo. This package is aimed at (1) supporting automation of IS workflow, (2) performing base and advance analysis for IS tracking (clonal abundance, clonal expansions and statistics for insertional mutagenesis, etc.), (3) providing basic biology insights of transduced stem cells in vivo. # Visit the package website You can visit the package website to view documentation, vignettes and more. - For the release version: [ISAnalytics Website release]( - For the devel version: [ISAnalytics Website dev]( # Installation and options `ISAnalytics` can be installed quickly in different ways: - You can install it via [Bioconductor]( - You can install it via GitHub using the package `devtools` There are always 2 versions of the package active: - `RELEASE` is the latest stable version - `DEVEL` is the development version, it is the most up-to-date version where all new features are introduced ## Installation from bioconductor RELEASE version: ``` r if (!requireNamespace("BiocManager", quietly = TRUE)) install.packages("BiocManager") BiocManager::install("ISAnalytics") ``` DEVEL version: ``` r if (!requireNamespace("BiocManager", quietly = TRUE)) install.packages("BiocManager") # The following initializes usage of Bioc devel BiocManager::install(version='devel') BiocManager::install("ISAnalytics") ``` ## Installation from GitHub RELEASE: ``` r if (!require(devtools)) { install.packages("devtools") } devtools::install_github("calabrialab/ISAnalytics", ref = "RELEASE_3_15", dependencies = TRUE, build_vignettes = TRUE) ``` DEVEL: ``` r if (!require(devtools)) { install.packages("devtools") } devtools::install_github("calabrialab/ISAnalytics", ref = "master", dependencies = TRUE, build_vignettes = TRUE) ``` ## Setting options `ISAnalytics` has a verbose option that allows some functions to print additional information to the console while they’re executing. To disable this feature do: ``` r # DISABLE options("ISAnalytics.verbose" = FALSE) # ENABLE options("ISAnalytics.verbose" = TRUE) ``` Some functions also produce report in a user-friendly HTML format, to set this feature: ``` r # DISABLE HTML REPORTS options("ISAnalytics.reports" = FALSE) # ENABLE HTML REPORTS options("ISAnalytics.reports" = TRUE) ``` # NEWS <details> <summary> Show more </summary> # ISAnalytics 1.7.4 (2022-10-04) ## VISIBLE USER CHANGES - Progress bars for long processing functions are now implemented via the package `progressr`, added a wrapper function for fast enabling progress bars, `enable_progress_bars()` - Introduced logging for issues in `HSC_population_size_estimate()` - signals eventual problems in computing estimates and why ## BUG FIXES AND MINOR CHANGES - Fixed minor bugs and typos # ISAnalytics 1.7.3 (2022-06-17) ## BUG FIXES AND MINOR CHANGES - All functions that check for options now have a default value if option is not set - `CIS_grubbs` function is now faster (removed dependency from `psych::describe`) ## NEW - New functions `CIS_grubbs_overtime()` and associated plotting function `top_cis_overtime_heatmap()` to compute CIS_grubbs test over time # ISAnalytics 1.7.2 (2022-05-23) ## BUG FIXES AND MINOR CHANGES - Fixed minor issues in `import_association_file()` - function had minor issues when importing \*.xlsx files and missing optional columns threw errors - Fixed bug in `as_sparse_matrix()` - function failed when trying to process an aggregated matrix ## NEW - Added 2 new utility functions `export_ISA_settings()` and `import_ISA_settings()` that allow a faster workflow setup # ISAnalytics 1.7.1 (2022-05-04) ## BUG FIXES AND MINOR CHANGES - Fixed minor issue in `compute_near_integrations()` - function errored when `report_path` argument was set to `NULL` - 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 - zipped examples were removed from the package to contain size. To compensate, the new function `generate_default_folder_structure()` generates the standard folder structure with package-included data on-demand - `transform_columns()` is a new utility function, also used internally by other exported functions, that allows arbitrary transformations on data frame columns ## MINOR CHANGES - `remove_collisions()` now has a dedicated parameter to specify how independent samples are identified - `compute_near_integration_sites()` now has a parameter called `additional_agg_lambda()` to allow aggregation of additional columns - `CIS_grubbs()` now signals if there are missing genes in the refgenes table and eventually returns them as a df - `outlier_filter()` is now able to take multiple tests in input and combine them with a given logic.

`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 # ISAnalytics 1.1.9 (2021-02-17) ## FIXES - Fixed minor issues in internal functions with absolute file paths & corrected typos # ISAnalytics 1.1.8 (2020-02-15) ## FIXES - Fixed minor issues in internal functions to optimize file system alignment # ISAnalytics 1.1.7 (2020-02-10) ## FIXES - Fixed minor issues in import_association_file when checking parameters # ISAnalytics 1.1.6 (2020-02-06) ## UPGRADES - It is now possible to save html reports to file from import_parallel_Vispa2Matrices_auto and import_parallel_Vispa2Matrices_interactive, remove_collisions and compute_near_integrations ## FIXES - Fixed sample_statistics: now functions that have data frame output do not produce nested tables.
