Problem with summarizing custom fields incrementally for multiple batches in one sample set
I have encountered a big problem when trying to force empower to do calculations for separate sample groups in one sample set. My example sample set looks like this attached. I need to use summarize intersample functions for every group (like average assay, number of samples in a group etc. for further custom fields calculations). Every calculation works fine with the first group but for the next ones empower uses e.g., average assay for all samples above summarize incrementally function not only those between last "summarize custom fields incrementally" and next spotted.
I tried to use "label reference" field in "summarize custom fields incrementally row but I can only put full label name i.e. trying to type something like "U*" will prompt window that this label doesn't exist (while putting e.g., "U11" works fine). I could label all samples per group "A", "B", "C" etc. but I need for samples to be separately recognizable in summarize custom fields calculations.
I have made a research on this forum and on other sites but couldn't find a simple solution for this, as it might seem, simple problem.
