Methods & Sampling

Trajectory data of Crepidula fornicata larvae swimming in 65mL still water flasks, analyzed from video footage. Two experimental controls were varied, resulting in four experiment types. Larvae were either previous fed or starved (Fed/St), and either in the presence of food or not in the presence of food (F/0). Five replicates (1-5) were conducted for each of the four conditions, resulting in 20 individual datasets. Further description and analysis of the data is published in DiBenedetto et al., 2020 (https://doi.org/10.1242/jeb.239178).

Data Processing Description

Video footage was processed in MATLAB. The centroids of the larvae were identified in each image. The centroids were linked to form trajectories using a predictive tracking algorithm. Linear and angular velocities were calculated along each trajectory, as described in DiBenedetto et al. 2020.

BCO-DMO Data Manager Processing notes:
* 20 csv files containing larvae tracks combined into one data table with added column to capture information in the file name(treatment variables, replication information).
* Numbers with 15 decimal places rounded to 5 decimal places.
* Original missing data identifier "NaN" is converted to compatible missing data identifers based on file type (matlab, netcdf, etc). 'nd' meaning "no data" is the default missing data identifier at BCO-DMO.
