concatenate textGrid data.

[georgid]

Concatenate TextGrid annotation files for the segmented files
into one-per-recording TextGrid annotation automatically:

1. install TextGridTools version 1.4.1 (either through GitHub or pip install --upgrade tgt). If you use pip, please make sure that it is really version 1.4.1 that is installed — if you get an older version, try again.
2. QUESTION:
   Because each big audio file to which the concatenated text grid corresponds starts with n seconds of silence, then I need to insert in the beginning n seconds of silence and then concatenate TextGrids where the first starts at timestamp = n.

To do this I tried this code:

shiftTime = 51.354230

tiers_ = []
os.chdir(pathInput)
tgtURI = '/Users/joro/Documents/Phd/UPF/ISTANBUL/goekhan/02_Kimseye_2_zemin.TextGrid'

from tgt.util import shift_boundaries
tg = tgt.read_textgrid(tgtURI)

tier = tg.get_tier_by_name('words')
tierShifted = shift_boundaries(tier, shiftTime,0)

tg.add_tiers(tierShifted)

tgOutURI = pathOut + 'Kimseye.TextGrig'
tgt.write_to_file(tg, tgOutURI)

However I get this error:

in ()
21
22 tgOutURI = pathOut + 'Kimseye.TextGrig'
---> 23 tgt.write_to_file(tg, tgOutURI)

391 if format in _EXPORT_FORMATS:
--> 392 f.write(_EXPORT_FORMATS[format](textgrid, **kwargs))
393 else:
394 raise Exception('Unknown output format: {0}'.format(format))

242 for tier in textgrid_corrected:
--> 243
result += ['"' + tier.tier_type() + '"',

244                    '"' + escape_text(tier.name) + '"',
245
                tier.start_time, tier.end_time, len(tier)]

AttributeError: 'Interval' object has no attribute 'tier_type'

RESPONSE:

the problem you encounter is solved easily. To add the shifted tier, you did the following:

tg.add_tiers(tierShifted)

This method, however, expects a list of tiers, not a single tier. You have to do the following instead

tg.add_tier(tierShifted)

or

tg.add_tiers([tierShifted])

concatenate in chrono order one after the other: first make sure they have same number of tiers

python ~/Downloads/TextGridTools-master/scripts/tgt-concatenate-textgrids.py -i 727cff89-392f-4d15-926d-63b2697d7f3f.TextGrid 727cff89-392f-4d15-926d-63b2697d7f3f_71.389446_82.591367.TextGrid -o 727cff89-392f-4d15-926d-63b2697d7f3f.TextGrid
