Description

• Concatenation & Normalization

  raw_data

  a flowSet with 3 experiments, each containing 2'500 raw measurements with a variation of signal over time. Samples were mixed with DVS beads capture by mass channels 140, 151, 153, 165 and 175.

• Debarcoding

  sample_ff

  a flowFrame following a 6-choose-3 barcoding scheme where mass channels 102, 104, 105, 106, 108, and 110 were used for labeling such that each of the 20 individual barcodes are positive for exactly 3 out of the 6 barcode channels.

  sample_key

  a data.frame of dimension 20 x 6 with sample names as row and barcode masses as column names. Contains a binary code of length 6 for each sample in sample_ff, e.g. 111000, as its unique identifier.

• Compensation

  ss_exp

  a flowFrame with 20'000 events. Contains 36 single-antibody stained controls where beads were stained with antibodies captured by mass channels 139, 141 through 156, and 158 through 176, respectively, and pooled together.

  mp_cells

  a flowFrame with 5000 spill-affected multiplexed cells and 39 measurement parameters.

  isotope_list

  a named list of isotopic compositions for all elements within 75 through 209 u corresponding to the CyTOF mass range at the time of writing.

• Differential Analysis

  PBMC_fs

  a flowSet with PBMCs samples from 6 patients. For each sample, the expression of 10 cell surface and 14 signaling markers was measured before (REF) and upon BCR/FcR-XL stimulation (BCRXL) with B cell receptor/ Fc receptor crosslinking for 30', resulting in a total of 12 samples.

  PBMC_panel

  a 2 column data.frame that contains each marker's column name in the FCS file, and its targeted protein marker.

  PBMC_md

  a data.frame where each row corresponds to a sample, and with columns describing the experimental design.

  merging_table

  a 20 x 2 table with "old_cluster" IDs and "new_cluster" labels to exemplify manual cluster merging and cluster annotation.
