How to name the columns of the csv file exported using 'Scope' or 'To File' ?

I am exporting a csv file using the following probe before a Scope/ToFile block.

The columns of the exported csv file are as shown below.

As you can see there are two columns with the same name ‘Capacitor voltage’. When I import this as a table in my MATLAB script for post-processing and analysis, it is a bit difficult to handle this situation. Is there a workaround where the above columns will be named something like ‘C1_Capacitor voltage’, ‘R2_Resistor current’, and ‘C2_Capacitor voltage’?

Hello,

You could place the components of interest inside a Masked Subsystem, and add their respective signals of interest as Mask Probe Signals, with your own custom names. Do you know how to do this?

Thanks for the suggestion, Kris!

I was able to do that. Although I have to carefully name each mask signal of my interest.

Let me pick your brain a bit more, please. I have created a masked subsystem out of a simple inductor as shown below.

Is there any way I can name the mask signals with a reference to the ‘Path’ of the probed component as highlighted red in the above figure? If this is possible, then I can use this masked subsystem as many times as I want in my circuit without worrying to name the probe signals individually. I am kind of hoping there is a solution here.

Hi again,

Unfortunately, I don’t think this is possible to include a path reference as part of the signal naming process. You will need to copy the path information into the signal name field manually.

Thanks,

Kris

Hi Kawsar,

I just wanted to update you that this has been fixed in PLECS 4.4.1. Please download the latest version here – release notes.1. The component signal tied to the Probe block now also displays the component name along with the signal name.

62. The To File block has a new parameter “Write signal names” that lets you choose whether CSV files are written with a header row containing the names of the input signals.

Additionally, there is a new From File block, that reads signal trajectories from CSV or MAT files.Regards,Manu

Thanks for the update Manu! This is very helpful.
