How to understand the error LFQ normalization error in Maxquant when doing Phosphor peptides LFQ ?

24 September 2021 1 5K Report

I performed analysis of my proteomics data in MaxQuant to compare phosphor peptides difference in two sample groups with LFQ intensity. However, error always occur when doing LFQ normalization, and the report show Index was outside the bounds of the array. How to understand the problem and what I should check?

Dear Minjie Tan,

what is the number of processors that you are using in your MQ analysis?

Sometimes the LFQ analysis crashes when there is a to large number of processors is selected in MQ.

Try to run with a lower number of processors.

Best,

Murat
