interop.py_interop_comm.incomplete_file_exception for runs with no indices/demultiplexing

[nicolazilio]

Hello there,

It appears that I can't open InterOp folders for runs where no demultiplexing occured, that is, where no indices were provided in the sample sheet

Traceback (most recent call last):
  File "/opt/pushParkourStats.py", line 112, in pushRunStats
    interop.read(
  File "/opt/conda/lib/python3.10/site-packages/interop/core.py", line 819, in read
    run_metrics = read_metric(filename, run_metrics=run_metrics, finalize=True)
  File "/opt/conda/lib/python3.10/site-packages/interop/core.py", line 849, in read_metric
    run_metrics.read_metrics_from_buffer(metric_group, data)
  File "/opt/conda/lib/python3.10/site-packages/interop/py_interop_run_metrics.py", line 334, in read_metrics_from_buffer
    return _py_interop_run_metrics.run_metrics_read_metrics_from_buffer(self, group, buffer)
interop.py_interop_comm.incomplete_file_exception: Insufficient data read from the file, got: 0 != expected: 9 for Index  v2
/io/./interop/io/format/metric_format.h::test_stream (250)

The offending line is this one.

I can provide you with an example, via DM.

Incomplete file exception does not mean nothing was parsed. We normally catch and ignore this exception except when we expect the run to be complete.
