To our users Please note that the HCV database site is no longer funded. We try to keep the database updated and the tools running, but unfortunately, we cannot guarantee we can provide help for using this site. Data won't be manually curated either.

Example of Preserving Removed Columns

Goal: You want to remove columns from an alignment but preserve an indication of which columns were removed. In this way you can preview what the Gap Strip/Squeeze operation has done to your alignment, and perhaps run the job again with different parameter settings.

Data: The alignment in the box below is in table format and contains differing numbers of gaps in various columns.

Settings: The tolerance for gaps has been set to 26%. In addition, the button marked "Preserve deleted columns" has been selected.
