I'm currently working on vaccine design by immunoinformatics approach, and have a plan to simulate immune response using C-ImmSimm webserver (https://kraken.iac.rm.cnr.it/C-IMMSIM/index.php?page=1). But every time I submit the job using my own FASTA amino acid sequence and default settings for the rest of parameters, the output status were "abnormal termination", hence the output went blank.
