Enter the world of immunology as a budding scientist tasked with identifying immune traces using T cell receptors. Use Atchley numbers to extract 4-residue long strips from each T cell receptor and evaluate them using a linear kernel to calculate a single number for each snippet. Your goal is to identify the highest-scoring snippet and determine if the individual has an immune trace. But beware, not all snippets contain relevant traces. Only the best immunologists can succeed!
