`exportIitYarp` generates YARP bottles with badly formatted bottle time-stamp

[aikolina]

Description

The timestamps of the bottles generated by exportIitYarp seem badly formatted. Here is an example:

0 7 288000000.11631 AE (911 4726831 1002 4784726 ...)

What I would expect is something like:

BOTTLE_ID YARP_TS AE (911 4726831 1002 4784726 ...)

However, I got an extra number before the AE tag which I was not expecting.

Details

Here are the steps I followed:

1. I dumped the raw data using the binary-dumper.

2. I imported the raw data using:

   imported = importIitYarp(filePathOrName = filePathOrName, tsBits = 30, convertSamplesToImu=False)

   and checked the time-stamp value for the first event:

   imported['data']['right']['dvs']['ts'][0] = 7.28800000e-05
   

3. I exported the imported raw data using:

   exportIitYarp(imported, exportFilePath= os.path.join(prefix, dataset_root, dataset_name + "_converted"), pathForPlayback= os.path.join(prefix, dataset_root, dataset_name + "_converted"), dataTypes = ['sample', 'dvs'], overwrite=True)

4. I checked the exported data.log and noticed that the bottle envelope was badly formatted.

   0 7 288000000.11631 AE (911 4726831 1002 4784726 ...)
   

So, it seems that the time-stamp in the exponential format (see point 2.) is exported as two separate numbers (see point 4.), and this causes an extra value before the AE tag.

Thanks @simbamford! Everything working as expected now. :)
