求助：构建粗粒化双层膜体系step 4报错 Residue 'DPSM ' was not found

学不会太难啦

各位老师们好，我想用charmm-gui的Martini Maker制作粗粒化的双层膜和蛋白，但是在第四步添加离子时报错说DPSM was not found，但是DPSM是我在里面选择的膜的组分，怎么会不存在呢？我该怎么解决这个问题？我上传了第三步生成的蛋白和膜的pdb文件，麻烦老师们帮我看看，感谢！

以下是报错信息：Evaluating: 0+1 Parameter: CNTRAND <- "1"   CHARMM>          if cntrand .gt. 100 stop ! replacement may not work.. stop here Comparing "1" and "100".
