PALMA-leafmov
Command-line leaf movement analysis tool for Arabidopsis thaliana
PALMA is a simple, command-line tool to determine rhythmic leaf movement behavior from time-lapse photography pictures of Arabidopsis thaliana. PALMA consists of two components: PALMA1 extracts leaf and cotyledon tip positions from time-lapse photography studies and parses them into .csv-files which are read by PALMA2. PALMA2 performs Fast-Fourier transformation and non-linear least squares fitting to determine the periods, amplitudes and phases of rhythmic leaf movements.
