由于剛學(xué)GMX,按照一個教程上的步驟模擬納米管的水輸運行為,我做的步驟如下: 第一步:由MS建立(6,6)144碳納米管,之后用gaussian轉(zhuǎn)換為pdb文件格式。 第二步:在gmxl力場文件中建立了n2t文件,指定納米管的成鍵,并在ffbon.itp文件中添加了碳納米管的一系列成鍵參數(shù)。 第三步:用g_x2top -f cnt.pdb -o swnt_6_6_144.top -ff gmx 生成top文件。 第三步:建立盒子,生成gro文件,命令為:editconf -f cnt.pdb -o cnt.gro -c -box a b c 第四步:加水genbox -cp cnt.gro -cs -o swnt_6_6_144_b4em.gro -p swnt_6_6_144.top 第五步:grompp -f em.mdp -c swnt_6_6_144_b4em.gro -p swnt_6_6_144.top -o index 在此出現(xiàn)錯誤,信息如下: processing coordinates...

這個警告的意思是說你的坐標(biāo)文件(gro)中的原子名稱和拓?fù)湮募╰op)中的原子名稱不一致,模擬將會使用拓?fù)湮募械拿Q。 你仔細(xì)檢查你的坐標(biāo)文件中的原子順序與拓?fù)湮募欠褚灰粚?yīng),如果是對應(yīng),而且你讓這些原子的名字按照拓?fù)渲械拿謥,這個警告可以忽略不管! 你的這個警告可以忽略 只是有2點兒不明: 1、為何你的gro文件中的resid 從0開始?我模擬的一般都是從1開始 2、為何你的gro文件中碳納米管沒有 resname ?
