T Cell Tracker

As a scientist in the future, you are tasked with identifying immune traces that can serve as biomarkers. Use the latest technology to sequence T cell receptors from patients and analyze 3D X-ray crystallographic structures of T-cell receptors bound to antigens to locate the relevant traces. Discard irrelevant portions and extract every possible 4-residue long strip from every CDR3 of a T cell receptor sequence. Represent each snippet using 20 Atchley numbers and calculate the frequency of each snippet. Evaluate each snippet using a linear kernel and find the highest score. Finally, process the highest score through a sigmoid function that converts the score into a probability between 0 and 1.
