APSC allows to convert protein sequence from different formats (as Fasta, PDB, Swiss-protein, Swiss-DNA) to another ones (as Fasta, Swiss-protein and Pure amino acid sequence). You do not have to think about input format at all. You can simply select all input files and program will recognize automatically in one step each file that contains amino acid sequence. Then you can export some or all loaded sequences to the requested format also in one step.
