Sequenza ERROR: Collecting GC information Error in (function (x, col_types) : unused argument (parallel = 1)

[Tanay]

Hi

I am using Sequenza to identify CNAs in tumor-normal files . A year ago I was able to generate the result using the below code. I have generated the binned file using bam2seqz followed by sequenza-utils seqz_binning parameter. However, it is now showing the below error while running sequenza in R (version 4.3.3).

> library("sequenza")

> setwd("/sequenza/result/IITK_P01_TD")
> data.file <- "IITK_P01_TD.small.seqz.gz"
> seqzdata <- sequenza.extract(data.file)
Collecting GC information Error in (function (x, col_types)  : unused argument (parallel = 1)

Please let me know how to solve it.
