Error in vecseq when running estimateTechnicalNoise

Dear chicagoTeam,

I am trying to use Chicago for analysis of CaptureC data. However, when I am running chicagoPipeline, I am getting an error message (see below). Do you have any idea why this and how I can fix it? I have not found the source code for estimateTechnicalNoise, otherwise I guess that I could just make the suggested changes (i. e. allow.cartesian)?

Thanks a lot for your help Best wishes Angelika Feldmann

*** Running estimateTechnicalNoise...

Estimating technical noise based on trans-counts... Binning baits based on observed trans-counts... Defining interaction pools and gathering the observed numbers of trans-counts per pool...

Preparing the data.....Error in vecseq(f__, len__, if (allow.cartesian || notjoin) NULL else as.integer(max(nrow(x), : Join results in 52261470 rows; more than 27846218 = max(nrow(x),nrow(i)). Check for duplicate key values in i, each of which join to the same group in x over and over again. If that's ok, try including j and dropping by (by-without-by) so that j runs for each group to avoid the large allocation. If you are sure you wish to proceed, rerun with allow.cartesian=TRUE. Otherwise, please search for this error message in the FAQ, Wiki, Stack Overflow and datatable-help for advice.
