我正在尝试使用 bbmap ( pileup.sh in= my.fa out=new.txt) 检查来自 illumina 读取的组装支架的测序深度。
使用Linux，我安装了java jdk，如您所见：
$ java -version
java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)
另外，我安装了bbmap模块。
当我尝试运行管道时：pileup.sh in= my.fa out=new.txt，出现此错误：
Error occurred during initialization of VM
Unable to allocate 207104KB bitmaps for parallel garbage collection for the requested 6627328KB heap.
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
我该如何修复这个错误？
