各位前辈:
本人最近在学习amber官网上关于用mmpbsa计算结合自由能的一个例子(http://ambermd.org/tutorials/advanced/tutorial3/)。
当我做到这一步时:$AMBERHOME/bin/mm_pbsa.pl extract_coords.mmpbsa > extract_coords.log,出现了下面的出错信息:
Use of uninitialized value in concatenation (.) or string at /usr/local/amber10/bin/mm_pbsa.pl line 22.

这是为什么呢?实在是想不明白,求高手指点,先谢谢大家啦!
