    NMR data 

    I’ve been considering what additional data will be needed for the animation/objects. I think some of the basic stuff can be calculated and stored in MySQL, things like:

    • distance travelled (per day, stored per nmr; cumulative since beginning of data)
    • speed (average per day; current – based on last x mins)
    • days alive (current – incremental until death)

    All these data points can be used as parameters in the animation.

    How can we see communal activity, such as nearest neighbours? We need to divide the nest into 6 zones, and note which zone each animal is in at any one time. The zones might be a better way of visualising the animals rather than the sensor points, as we can have them animating to simple rules within that zone area.

    From the zones we can see which animals are sharing a zone, and which animals are neighbours (in a touching zone). We can also calculate length of time in a zone which when summed will give us a break down of activity across the nest.

    i.e. a day in the life of animal 16 =
    zone A 20%
    zone B 5%
    zone C 40%
    zone D 15%
    zone E 12%
    zone F 8%

    We can then see if we can match the pattern of one animal to another based on which zone they are in and when.

    1st test – NMR tracking in lab (local version) 

    Today the iMac was deployed to track colony Omega (20 NMRs) using 7 sensors. The data is being stored on a local MySQL db.

    deployed code on github (misslake)

    estimated data logging (as determined with lights on):
    24 rows of non-blank data per 30 seconds
    scales up to around 70,000 per day if NMR movement frequency maintains this pace
    files size: MySQL dump of 41,000 rows = 1.6MB. scales up to around 40MB per million rows
    14.28 days per 40MB/million rows

    System left on, with display sleep (NOT system sleep).

    Friday 8th May – tested the MiniTracker II [https://www.avidid.com/products/minitracker-i but with an RS232 cable] device with the NMR colony and received adequate readings from nearly all critters that passed through the tube.

    The device does need resetting periodically – testing the timeout on this there appears to be no logical pattern, so as it is a low overhead I’ll send a character to each reader every 30 secs, and test this.
    How to test?

    • Establish the mean average frequency between readings
    • Look for a number of segments of time when no data is coming from the device, that is above this average frequency.

    Last week a total of six trackers were ordered and paid for. There is a possibility that we need an extra one if we want to establish time spent within the tubes and within each housing element.
