The gDRimport package is a part of the gDR suite. It
helps to prepare raw drug response data for downstream processing. It
mainly contains helper functions for importing/loading/validating dose
response data provided in different file formats.
There are currently four test datasets that can be used to see what’s the expected input data for the gDRimport.

load_manifest, load_templates and
load_results functions and supports different file
formats.

## data 5 data.table listPRISM, the Multiplexed cancer cell line screening platform, facilitates rapid screening of a broad spectrum of drugs across more than 900 human cancer cell line models, employing a high-throughput, multiplexed approach. Publicly available PRISM data can be downloaded from the DepMap website (DepMap).
The gDRimport package provides support for processing
PRISM data at two levels: LEVEL5 and LEVEL6.
LEVEL5 Data: This format encapsulates all information about
drugs, cell lines, and viability within a single file. To process LEVEL5
PRISM data, you can use the
convert_LEVEL5_prism_to_gDR_input() function. This function
not only transforms and cleans the data but also executes the gDR
pipeline for further analysis.
LEVEL6 Data: In LEVEL6, PRISM data is distributed across three separate files:
prism_data: containing collapsed log fold change data for viability assays. cell_line_data: providing information about cell lines. treatment_data: containing treatment data.
Processing LEVEL6 PRISM data can be accomplished using the
convert_LEVEL6_prism_to_gDR_input() function, which
requires paths to these three files as input arguments.
To process LEVEL5 PRISM data, you can use the following function:
Replace “path_to_file” with the actual path to your LEVEL5 PRISM data file. This function will handle the transformation, cleaning, and execution of the gDR pipeline automatically.
To process LEVEL6 PRISM data, you can use the following function:
Replace “prism_data_path”, “cell_line_data_path”, and “treatment_data_path” with the respective paths to your LEVEL6 PRISM data files.
The function installAllDeps assists in installing
package dependencies.
