Usually in my articles for the \documentclass[journal]{IEEEtran}, I use the description environment without getting any error, i.e. \begin{description} … \end{description}.
However, when I used the \documentclass{bioinfo} for the Oxford Bioinformatics journal template I got an error stating that the description environment is undefined.
Can anybody help me to figure out this issue?
