Segmentation fault for large datasets

[Shubhangi1397]

Hey, I ran multiple sequence alignments on protein sequences of length 7096 for largedatasets (1000's, 100,000's) on clustalO and kalign. I had cleaned the datasets i.e. removed sequences having BJOUXZ characters and duplicate sequences. Running MSA for 15,000 sequences and above gave me segmentation fault for building guide tree on kalign whereas, clustalO ran just fine. [2022-03-10 11:55:18] : LOG : Building guide tree. Segmentation fault

Could you share the sequences with me so I can reproduce the problem? Thanks

Hey Timo, Thanks for your email. I am currently working on SARS-CoV-2 ORF1ab protein sequences. I have removed the sequences consisting of ambiguous characters (BJOUXZ) and duplicate sequences. Here is the dataset. link: https://drive.google.com/file/d/1fBgjKxpmDXm7gfOYF8JhYIEr8GcF-VpE/view?usp=sharing I have been getting segmentation faults for sequences above 13k. Your input would be valuable. Many thanks Shubhangi Kandwal

Thanks! I think I identified the problem; working on a solution. This may take a few days.
