  Can you provide your text file?

  Do you get the error after you load your file?

  Notice three major changes below. The definition of disassemble2arrayBB() was just an extra step but probly not needed.

  int lngth = 10000; 
  int scaleX = 5;
  int scaleY = 2;

  thanks kfrajer errors are gone

  but now it seems like file does not actually loading

  full code down here, it should draw graphs based on data readings from file

  int lngth = 10000; 
  
  int scaleX = 5;
  int scaleY = 2;
  
  String fileName = new String();
  String[] lorem = new String[lngth];
  
  int[][] endArray = null;
  int[][] smoothArray = new int[lngth][10];
  
  drawGraph graph;
  fileLoad load;
  
  void setup() {
    noLoop();
    size(1800, 600);
    selectInput("Select a file to graph: ", "fileSelected", new File(dataPath("")));
  }

    if (selection == null) {
