获取软件
conda install -c bioconda prodigal
prodigal --help
很多软件都是依赖prodigal的，所以启动相应的环境即可，
比如：prokka, DRAM, checkv, BUSCO
都在用version 2.6.3

Reading in the sequence(s) to train...
Warning: ideally Prodigal should be given at least 100000 bases for training.
You may get better results with the -p meta option.
