Python - 远程拒绝权限

Question

我正在使用名为SPAdes-3.50-Darwin的程序并在服务器上运行它（我没有root访问权限），即使在我的本地计算机上运行正常，我也会收到以下错误：

   == Running read error correction tool: /export/home/james/Tools/SPAdes-3.5.0-Darwin/bin/hammer /export/home/james/package/output/pg/assembly_files/NA12877_S1_chr14_105900000-107300000/spades_files/3-49/corrected/configs/config.info

 errread, errwrite)
 File "/usr/lib/python2.7/subprocess.py", line 1327, in _execute_child
 raise child_exception
 OSError: [Errno 13] Permission denied

这与没有root权限有关吗？
