Why filter out empty labels from Intervals?

        if tierType == INTERVAL_TIER:
            while True:
                try:
                    timeStart, timeStartI = _fetchRow(tierData,
                                                      "xmin = ", labelI)
                    timeEnd, timeEndI = _fetchRow(tierData,
                                                  "xmax = ", timeStartI)
                    label, labelI = _fetchRow(tierData, "text =", timeEndI)
                except (ValueError, IndexError):
                    break
                
                label = label.strip()
                if label == "":
                    continue
                tierEntryList.append((timeStart, timeEnd, label))
            tier = IntervalTier(tierName, tierEntryList, tierStart, tierEnd)

Why wouldn’t I want the intervals exactly as they appear in the file?

Pulled it this morning, couldn’t be happier! Thanks for the quick help on this.

I’m working with forced alignment of a transcribed audio dataset- I have to have adjust the audio and textgrids to include a silence at the start and end.

I think perhaps this preprocessing behavior isn’t immediately intuitive- I suggest an optional ‘raw’ flag argument could allow for reading in everything in the file. Or perhaps an optional processor function could be supplied that would handle this sort of preprocessing.
