## OCCURRENCE

### ARB_NT/Tree/Modify branches/Scale branchlengths

## DESCRIPTION

### Scales all branches of the selected tree by a user-provided factor.

## NOTES

### Use this when ARB has misinterpreted branchlengths during import of a tree. That happens when one branchlength is slightly above 1.0 (i.e. when the treeing program has an error) in which case ARB has assumed that branchlengths are in range [0 .. 100] and has divided them by 100.

## EXAMPLES

### None

## WARNINGS

### None

## BUGS
