Jalview's menus and fonts are too small on my Windows machine !

When Jalview is run on WIndows machines with high resolution displays (e.g. 4K, retina, etc) resolution screens, you might find that all the menus, window titles, and alignment data are really tiny. That's because on high-resolution displays, all the windows and fonts have to be magnified so that you can read them, and the fix is to ask Windows to do the same for the Jalview application.

Instructions on how to do this can be found in several places on the 'net. Your milage may vary so please let us know if you are having problems via the jalview-discuss AT jalview.org mailing list !

See https://pivotce.com/2017/12/11/fix-java-applications-for-high-dpi-display/ for the following solution which should work for launching Jalview via webstart on machines with Java 8 installed.

  1. Close Jalview
  2. Find java.exe and/or javaw.exe likely found in C:\Program Files\Java\jre(version#)\bin.
  3. Right click on it and select -> Properties
  4. Go to Compatibility tab
  5. Check Override high DPI scaling behavior.
  6. Choose System for Scaling performed by:
  7. Click OK
  8. Relaunch Jalview

Fuzzy fonts in the alignment view on OSX Mojave (10.14.x)

On OSX Mojave, you may notice that sequences and IDs in the Jalview alignment window are hard to read. To fix this, first:

1. Save your work and shut down Jalview

2. Open a Terminal window (use spotlight or the Launcher and type 'Terminal' to locate the Terminal App), and type:

 

  defaults write -g CGFontRenderingFontSmoothingDisabled -bool NO

3. Start Jalview again and load an alignment to check that the fonts are now legible.

Can Jalview run with Java 9

Jalview is compatible with Java 9, but only via webstart, or with a modified command-line launch script. If you use the InstallAnywhere version of Jalview it will recommend you install Java 8.

If you have installed Jalview via InstallAnywhere and you cannot access JABAWS services (a dialog box appears after you start Jalview about this), then you can patch the Jalview installation.

On OSX: - Add two lines to the Jalview.app/Contents/Info.plist file after the line starting <string>-Xdock:icon=

Can't see databases in Database Chooser after selecting Fetch Sequences...!

If you are running Jalview 2.10.0 under Ubuntu or some other (possibly GTK based) Linux desktop, you may find that after opening the Sequence Fetcher, you are presented with a dialog box just showing 'OK' and 'Cancel' buttons, but nothing much else. The empty panel is due to an underlying problem with Java, but you can still choose from the list of databases with the keyboard !

I downloaded the Jalview Installer for OSX but the install application won't run

The OSX InstallAnywhere version of Jalview is downloaded as a ZIP archive (install.zip) which is normally unpacked automatically to create an application called 'install' that you can run. If nothing happens when you double click the application, then there are a few things that could go wrong.

Installer doesn't launch because it was unpacked with a third-party archive tool
