MSstatsShinny app with heavy files

[Borja Belda Palazon]

Dear all,

This is Borja from May institute 2026, I am trying my best to run MSstatsShinny app with high volume DIA-NN data (starting from files of ~500 MBA to heavy files of 2 Gb) and I always get stuck at some point during the data processing and summarization. Have you experienced these problems with this type of files before?

when the data is loaded and I try to summarize data and obtain the QC etc. I always obtain this message:

Warning: The select input "qc-which" contains a large number of options; consider using server-side selectize for massively improved performance. See the Details section of the ?selectizeInput help topic  

Thanks in advance,

Borja

 I saw in the Shiny documentation that this can happen when selectizeInput() loads too many choices client-side. Could you please check whether the input “qc-which” should be implemented with server-side selectize (server = TRUE in updateSelectizeInput)?
