请教gmx sasa在bash下运行报错

jia1012428

老师您好，我看了教程上面的gmx sasa -f md_0_1.xtc -s md_0_1.tpr -surface “group protein” -output ‘”Hydrophobic” group protein and charge {-0.2 to 0.2}; “Hydrophilic” group protein and not charge {-0.2 to 0.2}’这个命令，但是在bash下运行会报错，请问有例子作为参考吗。下面是错误提示，Error in user input:
Invalid command-line options
  In command-line option -surface
    Near '▒'
      syntax error
  In command-line option -output
    Invalid selection 'group'

以北京科音分子动力学与GROMACS培训班（http://www.keinsci.com/workshop/KGMX_content.html）里的1UBQ文件夹为例，在CentOS的终端里用毫无问题



要么你没写对，要么用了什么古怪的shell

老师，我双引号符号写错了，我用你之前回答别人的写法gmx sasa -f md_0_1.xtc -s md_0_1.tpr -surface 'group protein' -output '"Hydrophobic" group protein and charge {-0.2 to 0.2}; "Hydrophilic" group protein and not charge {-0.2 to 0.2}'，就没有问题。感谢感谢！
