string compare

[acm...@columbia.edu]

Hi Bonsai community,

I'm having some trouble finding a node that performs a 'string compare' logic. I have a list of different strings coming in through SerialStringRead and would like to catch a certain string and save the time stamp of its occurrence. I am sure there is a function for this already, but my searches so far were unsuccessful.

Thank you in advance for your help!

Hi Alice,

What do you mean by "string compare"? From your description, it seems like you want to parse the string. If that's the case, you can use the Parse operator for that. You can match a string against a fixed template and extract basic data types.

For example, the following pattern: %i-%i will parse two integer numbers separated by a hyphen.

Hope this helps.

I'm not sure that does what I want. Sorry for not explaining it better.

What I would like is that for example, whenever the string "lick" comes in through the serial, I want to detect it and safe a timestamp of the event.

Thank you for your fast help, as ever.

Ah, thanks for clarifying. In that case, it might be enough to just use the Equal operator to test whether the input string matches some fixed value.

 

After that you can use Condition, followed by Timestamp, to generate the output you want. You can use this pattern in multiple parallel branches.

 

Hope this helps.
