Thank you for the quick reply. Actually the output I get is:
ACTION OUTPUT:
DATASETS:
5 data sets:
H1[UU] "H1[UU]" (integer), size is 2000
HB_00001[UU] "HB_00001[UU]" (integer), size is 2000
HB_00001[UV] "HB_00001[UV]" (integer), size is 2000
HB_00001[Bridge] "HB_00001[Bridge]" (integer), size is 2000
HB_00001[ID] "HB_00001[ID]" (string), size is 2000
DATAFILE OUTPUT:
hb.dat: HB_00001[UU] HB_00001[UV] HB_00001[Bridge] HB_00001[ID]
hb.dat: Writing 2000 frames.
[runanalysis lifetime H1 [UU] out life.dat]
Error: lifetime: No data sets selected.
I find it a bit difficult to interpret the bracketed terms and use the right dataset.
