I am exporting a csv file using the following probe before a Scope/ToFile block. ![181](https://europe1.discourse-cdn.com/flex006/uploads/plecs/original/1X/2d2f28fc2ae6ed7dc012af72501b6b1cee72545c.png) The columns of the exported csv file are as shown below. ![181](https://europe1.discourse-cdn.com/flex006/uploads/plecs/original/1X/871baa1dbf2a67b763383f17f11054c124813dab.png) 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? Regards, Kris ---

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. ![181](https://europe1.discourse-cdn.com/flex006/uploads/plecs/original/1X/9e06dc048beab16542b34022cb24fd9d02edb07f.jpeg)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](https://www.plexim.com/download/release-notes).1. The component signal tied to the Probe block now also displays the component name along with the signal name. ![6](https://europe1.discourse-cdn.com/flex006/uploads/plecs/original/1X/cf412905e560e42248dd5da23b6a1837e1769c63.jpeg)2. 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.
