I'm new to lcm, and I deal with ROS, before I come here.
in ROS there is an application which could combine two ros bag into one and also has an application could split a ros bag into two.
thus, i wandering if there an application which could do same work for me

best regard.

Howe,

I'd try cross posting this to the user's group at https://groups.google.com/forum/#!forum/lcm-users , since this isn't necessarily an issue with the codebase.

To not leave you hanging, there's no built in tool with LCM to merge/split logs. What I've done is write a python script that pulls in all the LCM log headers from multiple logs into a pandas dataframe, and from there you can sort by however you want (usually by log timestamp), and then sequentially go through each event and copy them into a new logfile.

Here's a Python module that implements that kind of workflow:
