If i give command as =
g_dist -f md.xtc -s md.tpr -n index.ndx -dist 0.8
this prints out all the protein water distance within 0.8nm. The data printed
out is such that=

In the above data can be seen that the time frame is not continuos. i.e. only
the time at which the protein water distance within 0.8nm are shown. So is it
possible to do g_analyze on this?
None of the GROMACS tools are a replacement for thinking. What did you
want to do with a list of interactions over time that were within 0.8nm?
"Run g_analyze" is not an answer that will help you :)

Dear Gromacs Users,
i have data for the distance between the protein and water atoms within a cut
off of 8A for 5ns using the g_dist option. Now i want to use g_analyze on this
data. The time frame in the output data is not continuous because of the cut
off provided. So i would like to know how would the g_analyze would compute the
data.
I'm not clear on what you're trying to do. g_analyze performs simple
statistical operations (averages, error estimates) on the input data. If there
are discontinuities (which I do not understand the nature of), they come from
the g_dist data, not what g_analyze is doing.
Please provide a more clear description of what you are doing, including all
relevant commands, and examples of the data files, if necessary.
