Overview

This is our use case of cancer benchmarks. This document focuses on how to run the following three bundles in Codabench

• CODABENCH CANCER HETEROGENEITY DT#1 TRANSCRIPTOME PANCREAS
• CODABENCH CANCER HETEROGENEITY DT#2 METHYLOME PANCREAS
• CODABENCH CANCER HETEROGENEITY DT#3 IMMUNE CELL TYPES

Steps

1. Decompressing the original bundle

Unzip the bundle from its original zip file format into a folder.

2. Decompressing ingestion_program_1.zip

3. Modify the sub_ingestion.R file in the ingestion_program_1 folder.

Add lines 19 and 20 of code, and replace the underlined variable in line 25 with submission_program_dir

Two new lines of code have been added to allow the v2 compute worker to find the user-submitted program(program.R). （Because the v2 compute worker does not support searching for user-submitted code in subfolders.）

child_dir <- list.files(path=submission_program)
submission_program_dir <- paste0(submission_program, .Platform$file.sep, tail(child_dir, n=1))

// read code submitted by the participants :
.tempEnv <- new.env( )
source(
    file  = paste0(submission_program_dir, .Platform$file.sep, "program.R")
  , local = .tempEnv
)

4.Save the changes and re-zip the ingestion_program_1 folder.

Open the command line and go to the ingestion_program_1 folder.

Use the following command to package the modified folder as a zip file zip -r ingestion_program_1.zip *

Replace the latest compressed ingestion_program_1.zip file with the previous ingestion_program_1.zip file, and delete the ingestion_program_1 folder.

5. Recompress the modified original bundle.

Go to the directory at the same level as competition.yaml and execute the following command to compress the file zip -r Codabench_cancer_heterogeneity_DT#2.zip *

6. Creating competition with compressed bundles

7. Modify the default execution time

The default execution time is 10 minutes, but since these three bundles are time-consuming to execute, you have to turn it up.

We recommend that you adjust the time to the maximum value of 2147483647, so that the task will not time out and be forced to terminate by the compute worker.

Summary

This paragraph summarizes the results of the execution of three bundles in codalab v2.

CODABENCH CANCER HETEROGENEITY DT#1 TRANSCRIPTOME PANCREAS

https://www.codabench.org/competitions/147/ All three submissions were successful.

CODABENCH CANCER HETEROGENEITY DT#2 METHYLOME PANCREAS

https://www.codabench.org/competitions/174/ Two Submissions were successfully run, while the third failed due to insufficient execution time（We have now adjusted from the original 10,000 minute execution time limit to a maximum of 2,147483647.）

CODABENCH CANCER HETEROGENEITY DT#3 IMMUNE CELL TYPES

https://www.codabench.org/competitions/148/ 2 Submissions run successfully, 1 execution fails (screenshot below)
