Map-a-Bat and BatNav – frequently asked questions

Below are details of some of the issues most commonly encountered.

Analook/Anahead (7)

In Anahead “Chosen track doesn’t include first file”

Your AnaBat has been turned on before the GPS unit, or a GPS signal was not fixed before the survey commenced. This can often occur when you have tested your AnaBat unit earlier in the day before commencing the survey – i.e. before leaving the office.

Select only the files in the central Anahead column that are within the track times in the right hand column

Upon opening Anahead “An invalid argument was encountered”

Unknown. This error has appeared in several recent versions of Analook. Click OK. No known side effects.

In Anahead “Not all files included in chosen track”

Some of the AnaBat call times are outside of the GPS track times. Check you have selected the correct gps.txt file for your survey. Check that your data was downloaded with the correct TimeZone option.

Otherwise only select the calls that fall within the start and end times of the track file.

My AnaBat file times do not correspond to the survey times (and are not just an hour out of synch). The start times will likely be correct, but the final calls will appear to have been recorded after your survey was completed and the AnaBat switched off.

You have downloaded the data using an older incompatible version of CFCread. Download your data again from the CF card using the latest version of CFCread.

If you have erased your CF card you can download the data from the .DAT file saved in the original folder.

No gps.txt file in download folder

A) No GPS unit was connected or no GPS fix was received – your calls cannot be geo-located. Ensure that the GPS receiver is connected and has a signal for future surveys.

B) Generate GPS, Wave etc. option not selected in CFCread. Re-download your data and ensure that ‘Generate GPS, Wave etc.’ is ticked

C) Check that your firmware version doesn’t end with a ‘w’ – these versions are for Titley Scientific’s GML remote download system and won’t record the GPS data. Replace your firmware with the latest version ending in ‘g’.

My GPS times are wrong after upgrading my AnaBat SD2 to firmware 4061g

This is a known issue with firmware 4061g when used with older versions of CFCread. The timings of your AnalookW sequence files will not match the actual survey times, and the status.txt file may show timing errors in the region of -9223372036854 seconds.

No data has been lost and your survey data is fully retrievable. If you have old data that has already been saved simply point the new version of CFCread at the .dat file saved within your Analook sequence folder, and ‘download’ the data again to correct the timing errors.

How to obtain latest firmware/software.

My species labels have been shortened

There can be unexpected effects in Analook if you use non-alphanumberical characters in your species labels (e.g. – _ = + , . < > ~ and so on). Underscores and hyphens are used by some detectors to separate data in the species field so you cannot use these characters in your species names else they will get truncated – e.g. Pip_45 will be saved by Map-a-Bat as just Pip.

Only use letters and numbers in your Analook species names.

Google Earth (2)

Google Earth shows my route but no bat calls are displayed

The timeline start and end times have changed, often when you have changed which species are hidden/shown. Drag the start and end time sliders to the left and right sides respectively of the time line. See BatNav User Guide for details.

My AnaBat was in one location all survey but the GPS position moved

This is an artefact of the accuracy of the GPS system, which is affected by signal strength and position of the receiver. The position may wander around a fixed point by as much as 50m, especially in urban or cluttered environments as the signal will bounce off buildings, cliffs etc. Ensure that your GPS receiver has the clearest possible view of the sky.

Hardware (6)

No gps.txt file in download folder

A) No GPS unit was connected or no GPS fix was received – your calls cannot be geo-located. Ensure that the GPS receiver is connected and has a signal for future surveys.

B) Generate GPS, Wave etc. option not selected in CFCread. Re-download your data and ensure that ‘Generate GPS, Wave etc.’ is ticked

C) Check that your firmware version doesn’t end with a ‘w’ – these versions are for Titley Scientific’s GML remote download system and won’t record the GPS data. Replace your firmware with the latest version ending in ‘g’.

My GPS log stopped before the end of my survey but the AnaBat still continued to record bats

The internal batteries did not have enough power to run the GPS. The GPS needs a minimum of 4.5 volts, whereas the SD2 will run with a minimum of 4.0 volts (low battery warning @4.3V, power off @3.9V) The battery voltage will drop over the course of a survey, particularly when the batteries are towards the end of their life, and/or in cold conditions.

Always try to use fresh batteries at the start of each survey. If you’re using rechargeable batteries (most NiMH are 1.2V so 4x = 4.8V) the GPS unit may power down quickly.

SD2 users can check the log files on the CF card – they will indicate the battery voltage at the start and end of the recording session.

The GPS receiver light is always on

The GPS receiver cannot fix onto the satellite signals – the signal is blocked by buildings, interference, atmospheric conditions, or the USA has turned off the GPS system! Ensure that your GPS receiver has the clearest possible view of the sky, and allow up to 5 minutes for the receiver to lock on.

How to obtain latest firmware/software.

I’m using the latest firmware but no GPS data is saved

You have used the latest SD1/SD2 firmware with your Anabat but no GPS data is downloaded, even with ‘Generate GPS etc’ ticked in CFCread.

Please check that you are not using the Anabat firmware designed for use with the remote download GML system. This firmware will be expecting to have a modem connected to the serial port not a GPS unit, so will not save the GPS data, despite all other functions working correctly.

The current GML firmware versions are:

  • Anabat SD1 GML firmware = 402MW
  • Anabat SD2 GML firmware = 4061w (or 40xxw if updated after this FAQ was written)

Non-GML firmware will always end with ‘g’ – this is the version you should use on all Anabats that won’t be used with the GML system.

SD2 (8)

The error LED flashes on my SD2 after upgrading the firmware

The firmware upgrade has likely been successful, and the SD2 has booted expecting to find a data.dat file on the CF card. Insert an initialised CF card, or reformat and reinitialise the current CF card.

Error “Error 8 Writing to Bat File” in the CF log files. The AnaBat will have recorded no data, despite the lights indicating that the unit was recording

A known issue with SD2 firmware version v4055g. Visit the Titley Scientific website and upgrade to a later firmware version (minimum v4056g)
