## OCCURRENCE

### ARB_DIST

## DESCRIPTION

### Calculates a number of trees (specified at 'No. of trees') and shows the consensus tree.

### Each tree is based on a random set of columns. If you use a filter only the filtered columns will be picked randomly.

### The inner branches in that tree are marked by a percentage value, showing in how many of the bootstrapped trees that particular branch occurred.

### The higher that percentage is (best > 99%), the more likely that the branch is correct.

### Percentages above 99% are not displayed.

## NOTES

### If you specify '0' at 'No. of trees', the calculation won't stop. You may stop it by pressing 'KILL'. When you're then asked whether to wait or kill (after pressing the kill button), press 'WAIT' - or you'll kill the complete calculation.

## WARNINGS

### None.

## BUGS

### None.
