Hello guys, I am having difficulties to use canMessageImport (2022b Matlab version) to import .asc file with the header like this below. The .asc file was recorded with VN-1630 Box. I am using: message = canMessageImport(file,'vector',canDB,'OutputFormat','timetable'), but I get an empty result.

Could you guys please help me how I could work around that?

I'm having the same issue. Did you figure this out?

I had the same problem with some asc files. I solved it by converting the asc files to new asc files using canalyzer: menu -> tool-> logging converison. Below a screenshoot with the wrong original asc file (left) and a good one generated from it (right). The more notable changes are the base type and the extra info added at the end of the message (Length, BitCount, ID). I hope it helps
