How to Run (User)

This application is intended to run from the packaged Windows executable.

1. Open the project folder.
2. Go to dist.
3. Double-click the EXE file (example: tlog2chart_P3_v1.3.10.exe).

If startup takes some time, this is expected for a one-file EXE. You should see a splash/loading window during initialization.

Recommended User Workflow

1. Open a .tlog file (File -> Open).
2. Review plotted channels and select items to display.
3. Use Custom Scale to focus on the time range of interest.
4. Click Carry x to pass selected X-range into analysis.
5. Run Analysis.
6. Click Export to Word to generate a report.

FAQ (Common Questions)

1) Why does the app take time to open?

• This EXE is packaged in one file, so it needs time to unpack and load modules at startup.
• In v1.3.10, a splash/loading window is shown so you can see startup progress.

2) I loaded a .tlog file but no chart appears. What should I check?

• Confirm the file is a valid tlog text file and not empty.
• Check Unit Type and Band Filter settings.
• Open Select items to plot and make sure at least one channel is selected.
• Try Full Scale to reset the graph view.

3) Why is Export to Word disabled?

• Export to Word is enabled only after a successful Analysis run.
• Recommended order: load file -> set range -> Carry x -> Analysis -> Export to Word.

4) Why is first startup after rebuild slower than later runs?

• This can happen due to Windows cache and antivirus scanning behavior on new EXE files.
• Later launches are often faster after the first run.

5) The app icon looks different when running in IDE vs EXE. Is this normal?

• Yes, this can differ by launch method on Windows.
• For end users, the packaged EXE icon is the reference behavior.

6) Where can I find usage guidance inside the app?

• Help -> Instruction provides the recommended workflow.
• Help -> About shows version, release date, and product information.
