I was able to produce an output for searchGUI butcould not open it with peptide-shaker.
Could you please help me with this issue?

Meanwhile, I thank you for developing such useful tools,
Giovanni

Hi Giovanni,

It seems like you are using a very old version of PeptideShaker (v2.2.25). Please update to the most recent version (v3.0.11) to see if that solves the problem. You probably also want to update to the latest version of SearchGUI at the same time. Note that you may have to research your data in SearchGUI in order to guarantee compatible output.

Best regards,
Harald

Hi,

I got same problem with 3.0.11, in the start page increase the memory usage from Java, in my case using 10 GB (was 5) solved the problem.

Best,
Ahmad
