I just found the DBF-file, not the whole SHAPE, so I could not reproduce the problem with your data.</div><div class="">2. The DBF contains over 60.000 data sets, I think that is the network.</div><div class="">3. The screenshot you provided does not show a problem, but it looks like the plugin is still running (check the task manager to confirm it).</div><div class=""><br class=""></div><div class="">If you are using a very big network, than the plugin will slow down. Please read the detailed description of the plugin in the README on GitHub. In short:</div><div class="">The plugin hangs on the task „calculating transition probabilities“. Transitions are a pair of two candidates, i.e. points on the network that could represent trajectory points. For each transition the shortest route on the network will be calculated using the Dijkstra algorithm. Dijkstra steps through all nodes of the network to find the nearest parent node. If you are using a big network with a lot of nodes, this task needs some time. Especially if you have a lot of candidates and transitions (because of outliers, a too big maximum search distance or something else) and the task has to be repeated very often. So my advice for you is to use a spatial filter before you start the plugin:</div><div class=""><br class=""></div><div class="">1. create a line from your trajectory (e.g. using points to line)</div><div class="">2. create a buffer from the line (e.g. 500m)</div><div class="">3. clip the network using the buffer as clipping mask</div><div class="">4. run the plugin with the clipped network</div><div class=""><br class=""></div><div class="">I will integrate this task in the plugin in a future version. But the plugin is a free time project and actually I am working on another project. So the new version will take some time. Please try the described workaround.</div><div class=""><br class=""></div><div class="">Sincerely,</div><div class="">Christoph</div><div class=""><div><br class=""><blockquote type="cite" class=""><div class="">Am 23.05.2019 um 02:25 schrieb Chintan Advani <<a href="mailto:chintanadvani@gmail.com" class="">chintanadvani@gmail.com</a>>:</div><br class="Apple-interchange-newline"><div class=""><div dir="ltr" class="">Hey Christoph,<div class=""><br class=""></div><div class="">I did understood the yesterdays error. I inputted the maximum distance for path search as 0 which was not an acceptable value. However after inputting some random value, the software hangs at a particular stage while it calculates the transition probabilities.

<br class="">
Please provide more details about your problem. What did you do, what worked well, what did not worked as expected? Which version of the plugin and QGIS are you using? If the plugin throws an error, have a look into the QGIS-log. All exceptions of the plugin will be logged there. Give me as much as possible information, that I can reproduce your problem.<br class="">
