Here is the actual error message when trying to draw the walker output
that only has one point, "GRASS_INFO_ERROR(26696,1): Cannot open old
vector swwalkers401799@PERMANENT on level 2"<br>
<br>
thought that might be useful info?<br>

I am still investigating the outputs of various simulations I ran, and
may eventually answer my own question. However, I am hoping
someone with experience using this module can provide some insight or
guidance. <br>
<br>
First off, the r.sim.water is very cool! Especially an animation
sequence of walkers I saw in a document online by Helena Mitasova (<a href="http://www.ing.unitn.it/%7Egrass/conferences/GRASS2002/proceedings/proceedings/pdfs/Mitasova_Helena_2.pdf" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">
http://www.ing.unitn.it/~grass/conferences/GRASS2002/proceedings/proceedings/pdfs/Mitasova_Helena_2.pdf
</a>) that referenced this gif animation: (<a href="http://skagit.meas.ncsu.edu/%7Ejaroslav/centennial/anim/walkers.gif" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">http://skagit.meas.ncsu.edu/%7Ejaroslav/centennial/anim/walkers.gif
</a>)<br>
<br>
However, under various simulations I am getting no walker output for
some time steps through the simulation. Also, if the simulation
is not time-stepped no walkers are outputted. Using <a href="http://v.info" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">v.info</a> I am
getting one point for walker output. If I step through the
simulation 10 times, I get walker output on the 1st step, the 9th and
10th step, and only one walker point for all the other steps. In
other simulations that had 8 steps, I might have gotten walker output
for 2 of the 8 steps.<br>
<br>
I am still tuning the input parameters and checking results. If
anyone has some suggestions relating to this issue I would greatly
appreciate it!<br>
<br>
Thanks,<br>
Mark<br>
