The CytobankAPI package is designed to make interacting
with Cytobank
API endpoints easy via R. This document is an accompanying overview
of the package to learn concepts and see basic examples. View the Cytobank API Endpoint
Documentation for a comprehensive list of API endpoints for
Cytobank.
Within the CytobankAPI package, there are endpoints to
interact with advanced analyses via R. This documentation is an overview
of the different ways to utilize advanced analyses. To find more general
documentation on using the CytobankAPI package, view the Cytobank quickstart guide.
All advanced analyses are encapsulated within an object. This guide will be an overview of advanced analyses object structures:
Every advanced analysis is represented as an object. Creating a new advanced analysis will return an object that is passed to all of their other respective advanced analysis endpoints.
Important information to note:
show
endpoint, or update the advanced analysis with the current settings
using the update endpointviSNE_analysis <- visne.show(cyto_session, experiment_id=22, visne_id=214)
viSNE_analysis@name
#> [1] "My viSNE analysis example"
# Update the viSNE analysis object name directly
viSNE_analysis@name <- "My updated viSNE analysis name"
# Update the viSNE analysis using the 'visne.update' endpoint
updated_viSNE <- visne.update(cyto_session, viSNE_analysis)
updated_viSNE@name
#> [1] "My updated viSNE analysis name"There are common features for all advanced analyses:
Name: The name of the advanced analysis
Compensation ID: The compensation ID used for the advanced analysis
compensations.listChannels: The channels being analyzed within the algorithm (clustering or for general analysis)
Source experiment: The experiment the advanced analysis belongs to (all advanced analyses belong to an experiment)
Status: The state of the advanced analysis (new, running, done, canceled, etc.)
Available FCS files: FCS files available for the advanced analysis
Available channels: Channels available for the advanced analysis
Available populations: Populations available for the advanced analysis
There are special settings that pertain to each advanced analysis algorithm. These settings affect how the advanced analysis algorithm is ran. For each advanced analysis, you can view their respective settings and slots as shown below.

Directly update CITRUS settings via their slot names.
The following slots can be updated directly:
Required settings:
gateSetId from
CITRUS_object@.available_populationsOptional settings (defaults in parentheses):
# Set association models, plot theme and compensation
CITRUS_object@association_models <- c("sam", "pamr", "glmnet")
CITRUS_object@plot_theme <- "black"
CITRUS_object@compensation_id <- 22
# Bulk update the changes made to the CITRUS object
CITRUS_object <- citrus.update(cyto_session, CITRUS_object)The core functionality of CITRUS is establishing biological explanations for why samples between two or more groups differ from each other. CITRUS file grouping is used to categorize different files into these groups. There is 1 important setting to pay attention to:
group_name: the group that each file is associated with
The minimum number of samples per group is three. However, for more robust statistical analysis and to avoid spurious results, at least eight samples are recommended per group (see documentation for more information here)
There must be at least 2 groups in order to run a CITRUS analysis
Directly update CITRUS file grouping data.
# Set 'file1.fcs' through 'file4.fcs' to 'Group 1' and 'file5.fcs' through 'file8.fcs' to 'Group 2', exclude 'file9.fcs' from analysis

Directly update FlowSOM settings via their slot names.
The following slots can be updated directly:

to the FlowSOM analysis.

#> ...SPADE fold change groups are used to categorize different files into separate collections that will be compared amongst each other. There are 2 important settings to pay attention to:
Directly update SPADE fold change groups data.
# Set 'file6.fcs' and 'file7.fcs' as the baseline for 'Group 1'

Directly update viSNE settings via their slot names.
The following slots can be updated directly:
sampling_target_type
sampling_total_count
channels
compensation_id
iterations
perplexity
theta
seed
The following slots must be updated via helper functions:
population_selections (see the next section for how to update viSNE population selections)
# Set a new sampling target type, sampling total count, and compensation
viSNE_object@sampling_target_type <- "equal"
viSNE_object@sampling_total_count <- 150000
viSNE_object@compensation_id <- 22
# Bulk update the changes made to the viSNE object
viSNE_object <- visne.update(cyto_session, viSNE_object)Adding viSNE population selections is slightly more difficult because
the same file can be used in the analysis in combination with multiple
populations. Because of this complexity, the
visne.helper.set_populations helper function is used to set
files for a selected population.
Parameters for visne.helper.set_populations:
.available_populations slot)Set files for a specific population through the
visne.helper.set_populations helper function.
Setting files for a specific population will overwrite the files previously set for the population in question.
# Set files for different populations
viSNE_object <- visne.helper.set_populations(viSNE_object, population_id=1, fcs_files=c(44853))
viSNE_object <- visne.helper.set_populations(viSNE_object, population_id=2, fcs_files=c(44867,44868))
viSNE_object <- visne.helper.set_populations(viSNE_object, population_id=4, fcs_files=unlist(visne@.available_files[grep("file4|file5|file6", visne@.available_files$filename),]$id))
# Overwrite 'population_id=2' FCS file selection, note that 'file1.fcs' and 'file2.fcs' are in both 'Population 1', as well as 'Population 2'
viSNE_object <- visne.helper.set_populations(viSNE_object, population_id=2, fcs_files=c(44854,44855, 44853, 44867))
# Update the changes made to viSNE population selections
viSNE_object <- visne.update(cyto_session, viSNE_object)

The following example shows how to set up and launch a tSNE-CUDA analysis run.
# create a new dimensionality reduction analysis object and set the analysis type to be tSNE-CUDA
dimensionality_reduction_object<-dimensionality_reduction.new(cyto_session, experiment_id=22, analysis_name = 'use API to launch a tSNEcuda run', analysis_type = 'tSNE-CUDA')
# select clustering channels
dimensionality_reduction_object@clustering_channels<-list('CD4','CD8','CD3')
# Bulk update the change
dimensionality_reduction_object<-dimensionality_reduction.update(cyto_session,dimensionality_reduction_object)
# Launch the configured analysis run
dimensionality_reduction.run(cyto_session,dimensionality_reduction_object)
# Check the status of the launched analysis run
dimensionality_reduction.status(cyto_session,cyto_tsnecuda)
Directly update settings via their slot names.
The following slots can be updated directly:
.available_channels slot# Set a new sampling target type, sampling total count, and compensation
dimensionality_reduction_object@event_sampling_method <- "equal"
dimensionality_reduction_object@desired_total_events <- 150000
# Bulk update the changes made to the dimensionality reduction object
dimensionality_reduction_object <- dimensionality_reduction.update(cyto_session, dimensionality_reduction_object)These binaries (installable software) and packages are in development.
