While checking for deferentially expressed miRNAs after deep sequencing, i got some strange values like 1.79769e+308 or 1.79769e+308, which i can't understood. The rest of the values are +1, +2, +3 or -1, -2, -3, and are easy to understand. Can anybody tell me what do other values mean, or how to adjust them with the rest of the values?
