The data set aspects generated by 'hbond series' are [solutehb] for
solute-solute hydrogen bonds and [solventhb] for solvent-solute
hydrogen bonds (note that aspect information is listed for all actions
that use them in the cpptraj section of the Amber 14 manual). Since
you have named your data set H1 and you are looking for solute-solute
hydrogen bonds, you should refer to the data set as 'H1[solutehb]'. If
you're ever unsure as to how data sets are named you can refer to your
cpptraj output after a run. You should see a summary of data set names
etc in the DATASETS: part of the output, e.g.:
DATASETS:
20 data sets:
H1[UU] "H1[UU]" (integer), size is 100
H1[solutehb]:24 "GLU_13.O-VAL_2.N-H" (integer), size is 100
H1[solutehb]:104 "TYR_11.O-ILE_4.N-H" (integer), size is 100
...
So in summary the analysis command you want should look like:
runanalysis lifetime H1[solutehb] out life.dat
Hope this helps,
