    We don't know what you've done. Try it and see... the whole purpose
    is whether you like the form of what you see, right?<br>

I want to follow the workflow regarding to

for the second step I enter the command as below:
trjconv -f mdwhole.xtc -s md.tpr -dump 0 -o 1stframe.pdb

But I get the error:
&nbsp;Index[232] 235 is larger than the number of atoms in the
trajectory file (234). There is a mismatch in the contents
of your -f, -s and/or -n files

I don't have any index file, so what this error is talking about?</pre>

                <br>
                Then it must mean there's a mismatch in the contents of
                your -f and -s files... each must refer to the same
                system. Something about your past management of these
                two files makes your intended operation a nonsense, but
                we can't know what. If, for example, you chose xtcgroups
                in your .mdp file as something other than System, then
                they do not.<br>
