## OCCURRENCE

### ARB_NT

## DESCRIPTION

### Many functions of ARB expect all sequences of an alignment to be of the same length (Note: "length" doesn't mean "number of bases" here).

### Bringing all sequences to the same length (by adding gaps at the end of the sequence) is called "formatting".

### This prompt pops up whenever any alignment is unformatted and so provides an easy way to format your sequences.

## NOTES

### This function is also available in ´Alignment Administration´.

## EXAMPLES

### None

## WARNINGS

### None

## BUGS

### No bugs known
