Settings

The settings menu can be accessed using the “Settings” button in the main menu.

Settings are automatically saved when you return to the main menu. Changes are persistent between closing and re-opening Ziplign.

The options are:

  • Theme: the color theme can be changed from the default “Light” to various other themes.

  • Open Ziplign data folder: this will open your file manager at the built-in folder where Ziplign stores user data. This can be useful when debugging or when uninstalling Ziplign. In normal circumstances, you probably won’t need to use this.

  • Mouse wheel sensitivity: increase or decrease the amount of zoom when moving the mouse wheel. The default is “1”. The number chosen here is multiplied by an internal value for each mouse wheel movement. This means to move half as much, set the option to 0.5. To double the amount moved, set it to 2. If you want to turn it off completely, then set it to 0 (zero). Large values are not recommended, because one wheel movement will make Ziplign jump straight to maximum or minimum zoom.

  • Invert mouse wheel: use this to swap the effect of up/down on the mouse wheel, if you think zoom happens in the wrong direction

  • Trackpad zoom sensitivity: change the sensitivity of two-finger up/down movement to zoom using a trackpad. Similarly to the mouse wheel description, think of this as a multiplier, with the default being 1.

  • Invert trackpad zoom: use this to swap the effect of up/down on the trackpad, if you think zoom happens in the wrong direction

  • Trackpad left/right sensitivity: change the sensitivity of two-finger left/right movement.

  • Trackpad pinch sensitivity: change the sensitivity of pinch-zoom gesture on a trackpad.

  • Share BLAST usage with NCBI: by default, the command line BLAST program sends some data to the NCBI, as described in their privacy statement. By default, Ziplign turns off this setting so that no data is shared. You can turn it back on if you choose.

  • Max BLAST matches on screen: the maximum number of BLAST matches to show. Displaying too many will significantly impact memory usage. The default of 500 should be enough - a lot more than this and the screen ends up filled in to the point where it is impossible to see anything useful.

  • FASTA line length: the length of each line when copying/pasting sequence. Must be a non-negative integer. Put zero to have no line breaks in sequences.
