I need to do water channel simulations... I have two gro files with me...one for wall atoms and one for water atoms...assuming the co-ordinates of atoms are appropriate, I just need to rename the indices of each atom appropriately and append one file to another....I plan to do it by hand...but it will be great if there is an automatic way of doing it in gromacs?


This is a simple task that can be done with the Unix 'cat' command. Thus there is no Gromacs tool that reproduces this function. A few seconds with a text editor after concatenation to remove unnecessary title lines and box vectors and you're done, assuming (as you've said) that all the coordinates are appropriately defined. The whole process probably takes less typing than sending this email :)
