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

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
