Hello,

adjustRtime gave me the following errors when attempting with xdata = adjustRtime(xdata, param = ObiwarpParam(binSize = 0.6))

Error in manager$availability[[as.character(result$node)]] <- TRUE : wrong args for environment subassignment
Error in serialize(data, node$con) : error writing to connection

I tried register(SerialParam()) as suggested in #766 but ended up with the "R session aborted" error.

Below are the steps I took prior to performing alignment:

## Load data
raw_data = readMsExperiment(spectraFiles = files, sampleData = phenodata)

## Subset based on retention time
raw_data = filterRt(raw_data, c(60, 1000))

## Perform chromatographic peak detection in this section
## Peak detection parameters
cwp = CentWaveParam(
  peakwidth       = c(16.25, 57.75), # expected approximate peak width in chromatographic space
  ppm             = 10,            # maximal tolerated m/z deviation
  noise           = 1000000,          # minimum intensity required for centroids to be considered
  snthresh        = 10,              # defining the signal to noise ratio cutoff
  mzdiff          = -0.0065,         # minimum difference in m/z dimension required for peaks with overlapping retention times
  prefilter       = c(3.7, 100),       # Mass traces are only retained if they contain at least 3 peaks with intensity >= 200
  mzCenterFun     = "wMean",         # function to calculate the m/z center of the chromatographic peak
  integrate       = 2,               # Integration method, for 2 the descent is done on the real data
  fitgauss        = TRUE,            # whether or not a Gaussian should be fitted to each peak
  verboseColumns  = FALSE)           # whether additional peak meta data columns should be returned

## Peak detection on the full data set
xdata = findChromPeaks(raw_data, param = cwp)

## Merge neighboring chromatographic peaks
mpp = MergeNeighboringPeaksParam(
  expandMz = 0.0005, 
  expandRt = 5, 
  ppm = 10) 
xdata = refineChromPeaks(xdata, mpp)

For your information, print(object.size(xdata), unit = "MB") reported 40.4 Mb
