Question: How do I set the STAR limitGenomeGenerateRAM parameter in cellranger mkref? The STAR genomeGenerate steps exits with the following message:
EXITING because of FATAL PARAMETER ERROR: limitGenomeGenerateRAM=17179869184 is too small for your genome
SOLUTION: please specify limitGenomeGenerateRAM not less than 20164143146 and make that much RAM available
Answer: Please set the cellranger mkref --memgb parameter. The value set here (in GB) will be passed to the STAR genomeGenerate parameter limitGenomeGenerateRAM.
