## OCCURRENCE

### ARB_IMPORT

## DESCRIPTION

### This input format reader should read every sequence format, but:

- removes all other information
- maybe adds additional words to the beginning or end of the sequence

### The final ID of the species will be 'spec#', where '#' is a numerical number. You should 'Synchronize species IDs' as soon as possible.

### INTERNAL

This format scans the file for long strings containing more than fifty percent ACGTUN-. characters. All other words are deleted.

## NOTES

### There is no autodetection of this format. No additional information is read. No alignment is preserved. Subsequences with more then 30% ambiguities are removed.
