Description

Hello, I have an issue with the concatenate function from the GUI. A little context for my use case: I'm measuring a lot of data with INCA (100+GB uncompressed), saving it as a compressed mf4 file, version 4.10. Afterwards I want to merge/concatenate this data, to use the whole file in Simulink for simulation purposes. The problem that I have, is that some signals will end up with the wrong data for the wrong signal name --> data and signal name get mixed up. e.g. channel A has the data of channel B and channel B has the data of channel A after the concatenation. The names of the channels do not match up, with their original name. I checked the original files are ok, here signal names and data match up. I also merged the files with another tool, here there is no mixup, but it is very slow and cannot write compressed mf4-files, resulting in huge merged files (100+GB) whereas asammdf can merge it with a file size of 3+GB. I would very much like to use asammdf, but I cannot if my data ends up corrupted/mixed up.

I hope you can help me with this

If you need any more information, don't hesitate to ask.
