ipdSummary: AssertionError Child process exited with exitcode=1

Hi,

I am having trouble running ipdSummary (SMRTLINK version 11.0.0146107) although I am (presumingly) using all the right inputs.
Reads were produced with Sequel II sequencer.

This is the command I am running:
/usr/prog/GX/tools/src/pacbio/smrtlink/v11.0/smrtcmds/bin/ipdSummary aligned.bam --reference reference.fa --identify m6A --gff basemods.gff

Which gives me the following error:
Process KineticWorkerProcess-1: Traceback (most recent call last): File "/usr/prog/GX/tools/src/pacbio/smrtlink/v11.0/install/smrtlink-release_11.0.0.146107/bundles/smrttools/install/smrttools-release_11.0.0.146107/private/thirdparty/python3/python3_3.9.6/lib/python3.9/multiprocessing/process.py", line 315, in _bootstrap self.run() File "/usr/prog/GX/tools/src/pacbio/smrtlink/v11.0/install/smrtlink-release_11.0.0.146107/bundles/smrttools/install/smrttools-release_11.0.0.146107/private/thirdparty/python3/python3_3.9.6/site-packages/kineticsTools/WorkerProcess.py", line 151, in run self._run() File "/usr/prog/GX/tools/src/pacbio/smrtlink/v11.0/install/smrtlink-release_11.0.0.146107/bundles/smrttools/install/smrttools-release_11.0.0.146107/private/thirdparty/python3/python3_3.9.6/site-packages/kineticsTools/WorkerProcess.py", line 127, in _run result = self.onChunk( # pylint: disable=assignment-from-none File "/usr/prog/GX/tools/src/pacbio/smrtlink/v11.0/install/smrtlink-release_11.0.0.146107/bundles/smrttools/install/smrttools-release_11.0.0.146107/private/thirdparty/python3/python3_3.9.6/site-packages/kineticsTools/KineticWorker.py", line 121, in onChunk perSiteResults = self._summarizeReferenceRegion( File "/usr/prog/GX/tools/src/pacbio/smrtlink/v11.0/install/smrtlink-release_11.0.0.146107/bundles/smrttools/install/smrttools-release_11.0.0.146107/private/thirdparty/python3/python3_3.9.6/site-packages/kineticsTools/KineticWorker.py", line 230, in _summarizeReferenceRegion (caseChunks, capValue) = self._fetchChunks( File "/usr/prog/GX/tools/src/pacbio/smrtlink/v11.0/install/smrtlink-release_11.0.0.146107/bundles/smrttools/install/smrttools-release_11.0.0.146107/private/thirdparty/python3/python3_3.9.6/site-packages/kineticsTools/KineticWorker.py", line 449, in _fetchChunks rawIpds = self._loadRawIpds(hits, start, end, factor) File "/usr/prog/GX/tools/src/pacbio/smrtlink/v11.0/install/smrtlink-release_11.0.0.146107/bundles/smrttools/install/smrttools-release_11.0.0.146107/private/thirdparty/python3/python3_3.9.6/site-packages/kineticsTools/KineticWorker.py", line 484, in _loadRawIpds rawIpd = aln.IPD() * factor File "/usr/prog/GX/tools/src/pacbio/smrtlink/v11.0/install/smrtlink-release_11.0.0.146107/bundles/smrttools/install/smrttools-release_11.0.0.146107/private/thirdparty/python3/python3_3.9.6/site-packages/pbcore/io/align/BamAlignment.py", line 49, in f return self.baseFeature(featureName, aligned, orientation) File "/usr/prog/GX/tools/src/pacbio/smrtlink/v11.0/install/smrtlink-release_11.0.0.146107/bundles/smrttools/install/smrttools-release_11.0.0.146107/private/thirdparty/python3/python3_3.9.6/site-packages/pbcore/io/align/BamAlignment.py", line 536, in baseFeature assert len(data) == self.peer.rlen AssertionError Child process exited with exitcode=1.

I alinged my reads using pbmm2:
pbmm2 align reference.fa kinetic_reads.bam aligned.bam --sort

I also tried it with a 0.3 subset of my bam files, but it still gave the same error message. Feedback would be much appreciated, thanks already!

In case my set up is not suitable for this ipdSummary, I would also be happy about suggestions for alternative/better tools with similar functionalities. I am mainly interested in the detection of 6mA modified bases.
