VASIC Data Analysis is a data processing script utilizing the MATLAB environment for processing and visualizing data acquired from a VASIC device. This program reads all properly formatted *.csv files from a single directory and applies various filters to the data before generating a final output folder containing a collection of descriptive statistics. There are 3 levels of filtering applied to the data in sequence and controlled by 3 input parameters the user is prompted for at program startup: 1. Filtering readings without a minimum of X (default 2) data points 2. Filtering data points where the summation of both platforms is outside of ± X% (default 25%) of the calculated bodyweight 3. Filtering weight readings where the weight measurement on either platform is <X% (default 3%) of the calculated bodyweight The final output folder name is generated from the dates of the files processed and is formatted as follows: Results_[Start_<STARTDATE>_End _<ENDDATE>] with <STARTDATE> and <ENDDATE> being replaced by the appropriate start and end dates of the files processed. The final output folder top level structure and descriptions are as follows: 1. Access_Stats: directory containing summary statistics of the rodents' average access times and number of access events 2. Figures: directory containing images depicting individual data files' time course summaries and weight bias histograms 3. LR_Differences: a directory containing absolute weight bias summary statistics for raw data and each level of filtering in sequence (ie. Filter3 data has been filtered by Filter1, Filter2, and Filter3). Also contains summary statistic files for the number of incidents where Filter3 has eliminated data points (total number of data points filtered). 4. Normalized_LR_Differences: a directory containing weight bias summary statistics normalized to the rodents' calculated bodyweight for raw data and each level of filtering in sequence (ie. Filter3 data has been filtered by Filter1, Filter2, and Filter3). 5. Errors.txt: a text file listing any files in which an error occurred during data processing. 6. Log.txt: a text file listing a summary of the dates processed and the files read. 7. Settings.txt: a text file listing the input parameters used to generate the processed data files. 8. Weights.csv: a *.csv file listing the calculated bodyweight of each rodent on each day.
