\label{fig:4}  \textbf{ \emph{DmCa\textsubscript{v}3\textsuperscript{Gal4}} mutant shows rhythmic circadian locomotion and transcriptional oscillation of \emph{period}.}  \\  \textbf{(a)} Averaged activity profiles of second day of three LD cycle (LD, left panel), second day of DD cycle (DD, middle panel) and throughout the behavioral analysis (2 LD + 7 DD) are shown.  White, black and gray bar denote light phase, dark phase and subjective light phase, respectively.  The number of flies (n=37-54) , period (n=26-50), power of rhythmicity (P-S) and percentage of rhythmic flies (rhythmicity) are indicated in right panel.  Mann-Whitney U test for period (*p$<$0.05) and welch's t-test for P-S (***p$<$0.001).   \textbf{(b)} Transcriptional oscillation of \emph{period} gene in \emph{DmCa\textsubscript{v}3\textsuperscript{Gal4}} in DD. rp49 was used for normalization.  Data are represented as mean $\pm$ SEM.  a.u., arbitrary unit.            diff --git a/figures/Fig_4/size.tex b/figures/Fig_4/size.tex  deleted file mode 100644  index d638dc3..0000000  --- a/figures/Fig_4/size.tex  +++ /dev/null
