I am having the same problem now and I can’t figure out how to do this.
Has anything been done in this direction?
Right now I am using a simple script (awk/sed) to remove columns of gaps from the alignment and loading multiple files into jalview (ie: original file + gaps over 90% deleted + gaps over 75% deleted). Does anybody have a better solution?
Thanks very much in advance
Rafa
Hi Rafael.
We’re actually working on a new dialog for doing exactly this kind of operation. It currently works on the alignment annotation rows, but could easily be extended to work on other (non-visible) column wise properties such as gap percentage.
Try the jalview development version and look under the ‘Select’ menu to try out the new dialog. Any comments/requests can be added over at

Hi Rafa,
I have installed the development version to try this out, but I can’t see the “select by annotation” menu. I am running the mac version.
Try this build:
http://www.jalview.org/builds/develop/webstart/jalview_2G.jnlp
The new dialog is opened from the menu option at the bottom of the 'Select' drop down menu.
Currently, Jalview doesn't show the number/proportion of gaps as an annotation row that can be used to mark selections... we'll have a think to see how we can do it !
