SUMMARY

The discussion focuses on optimizing a MATLAB script for data analysis by allowing users to either input a filename directly or use the uigetfile dialog for file selection. The proposed solution involves modifying the script to check if a filename is provided; if not, it triggers the GUI dialog. Users are encouraged to explore command-line options for flexibility, as illustrated by the example using "script -g" for GUI and "script -f /location/to/file.dat" for direct file access.

PREREQUISITES
  • Familiarity with MATLAB scripting
  • Understanding of command-line arguments
  • Basic knowledge of GUI functions in MATLAB
  • Experience with data analysis workflows in MATLAB
NEXT STEPS
  • Research how to implement conditional file opening in MATLAB scripts
  • Learn about MATLAB's uigetfile function and its parameters
  • Explore command-line argument handling in MATLAB
  • Investigate best practices for structuring MATLAB scripts for user input
USEFUL FOR

This discussion is beneficial for MATLAB users, data analysts, and developers looking to streamline their data analysis scripts by integrating file selection methods.

Hi all

1. Homework Statement

I have a function script for doing some analysis of data from a text file and making some plots. My script takes the filename as an input argument - this is very helpful for running the analysis over multiple files and replicating results.

However, I have also found it helpful to be able to browse for the file using the command uigetfile.

So I have two versions of the same analysis script: one that requires a filename and one that opens a dialog box. This quite inefficient and awkward and it would be great if I could use a single script.

The ideal solution would be to have the code branch so that if a filename is provided that file is opened as normal, else a dialog box would appear if no name was provided (i.e. an empty argument.)

The Attempt at a Solution



I've googled around and searched mathworks, but have not found anything that helpful. Would anyone be able to point me in the direction of a solution?

Thanks for your help.BM

You could try to build something like options in command line programs.
For example use
Code:
script -g
to use the GUI dialog (or make that the default) and use
Code:
script -f /location/to/file.dat
whenever you know where to find the file.

I must say that I don't know how MATLAB handles these kind of things, the above idea, although the link above might give you further leads.

The advantage of the mentioned method is that you can use multiple options at once without bothering about the position.
So
Code:
script -o ExtraOption -f file
does the same as
Code:
script -f file -o ExtraOption

Edit;
added some information for doing this in C, it might give you an idea of how to implement this.
