spectrum, sequence batch size
The value is a non-zero integer.
When X! Tandem reads sequences from a source file, such as a FASTA file, it reads in a "batch" of sequences at once. The value of this parameter sets the number of sequences loaded in as a "batch". Typically, a value near 1000 is about the best trade off between efficiency of loading sequences in from a file and using too much computer memory to store the sequences.
As batches of sequences are processed, the console display (and log file, if desired) display a character as each batch is finished. Setting the value of this parameter to 1 will display a character for every sequence.
