[Benie140902]

As i am currently working on srsRAN with matlab i was successfully able to analyze PUCCH and PUSCH but unable to Analyze Resource Grid and PRACH even though i have referred help srsResourceGridAnalyzer and srsPRACHAnalyzer

Hi @Benie140902,
can you be a bit more specific? Can you report the error you get or explain in few words what you tried and the issue you're facing? Otherwise it's very difficult to help you without info.

Error using srsPUSCHAnalyzer
Incosistent configuration: the computed TBS is 4608, the provided one is 4224.

that has been sorted sir but the above error is there whenever i run srsPUSCH Analyzer how to overcome it sir but this was not the case initially

Hi @Benie140902,
you're right, the srsParseLogs is a bit outdated, as far as the PUSCH is concerned, we'll fix it ASAP. Please find a patch below, in the meantime.

After the patch, srsPUSCHAnalyzer works well for me, as well as srsPUCCHAnalyzer (for Formats 1 and 2) and srsResourceGridAnalyzer. At the moment I can't try srsPRACHAnalyzer, sorry, I let you know next week.

Hi @Benie140902,

I've just tried the PRACH analyzer and it seems to work.
