The conversation between human and AI assistant.
I work on volume reconstruction in electron microscopy. I want to convert from PDB (.ent) file to a VOL file (.vol). But to read the vol file in MATLAB, I need some information about the vol file (like size, offset, etc.). How can I get that information about the VOL file?
Yes, please. Can you tell me more about how to download and use libvol?
You can download libvol from the official website or GitHub repository. Once you have downloaded the library, you need to add its path to your MATLAB workspace by using the "addpath" function. 

Then, to read the VOL file, you can use the "vol_load" function, which takes the path to the VOL file as an argument and returns a struct containing the VOL data. You can also use the "vol_info" function to get size and offset information about the VOL file.

Is there anything else I can help you with?
