STAR建索引terminate called after throwing an instance of 'std::bad_alloc

When STAR builds the index of the norway spruce, because the Genome is too big, there is always an error such as terminate called after throwing an instance of 'std::bad_alloc'. After Google, I changed the command to

STAR --runMode genomeGenerate --runThreadN 20 --genomeFastaFiles Pabies.fa  --genomeDir STAR_index --limitGenomeGenerateRAM 80000000000（运行内存加到80G） --genomeChrBinNbits 11（If you are using a genome with a large > 5,000 number of references (chrosomes/scaffolds), you may need to reduce the --{genomeChrBinNbits to reduce RAM consumption. The following scaling is recommended: --genomeChrBinNbits} = min(18, log2(GenomeLength/NumberOfReferences)). For example, for 3~gigaBase genome with 100,000 chromosomes/scaffolds, this is equal to 15），所以挪威云杉12G的基因组需要log2(120,000,000,000/10,253,694)=11
