We run TFASTA (version 1.4a of February 1990) on a PC and found that the 
program crashes when it encounters entry ECG24 (AC: K01130) in the EMBL data 
base. The sequence length of this entry is 5 nt. We had to regularly delete 
this entry in new releases of the data base. I therefore asked Rainer Fuchs 
at EMBL a while ago whether it would be possible to remove this entry,
which is probably of no informational value to anyone.

(BTW: We also use Fasta - in batch runs - on a PC to search the whole data 
base and find it very convenient. The average run takes about 20 minutes 
so that quite a number of jobs can be done over night. We mainly use mail-fasta
to run our sequences against new entries.)
