Step	Problem	Cause	Solution
Case	When disease name is clicked, no sample shows up	The system is still loading the data	Wait for ~20 s for samples to be loaded
	Not all samples are selected in the table	The system is still loading the data; by default, all samples should be selected	Wait for ~20 s for samples to be loaded
Control	After clicking ‘compute control samples’, the page is inactive and could not respond	Depending on the number of case samples, it usually takes within 2 min to finish. It might get slower if many jobs are running	Wait for a few minutes and restart the job
Output	Job status is ‘Complete’, but some result files are missing	The system will change the status to Complete when all the key files are created. However, the job is still running to create supplementary files	Wait a few minutes for the system to assemble the output files
Upload data	No result file is created	Input file does not conform to the required format	Recreate the input file following the example file format. Column names include at least log₂FoldChange and Symbol
