在Agilent双通道芯片标准化课程中有如下代码：

files = list.files(workdir, pattern = "GSM")

files

RawData=read.maimages(files=files,source="genepix")

show(RawData)

我用的GSE8205的 Scan protocol 为 Axon 4000B scanner. Both the 635nm (red, Cy5) and 532nm (green, Cy3) channels are scanned simultaneously at 100% laser power, the PMT set between 600 and 950. Slides are scanned at a resolution of 10micron

我将课程代码中的 genepix 改成 axon，则显示如下情况：

Error in match.arg(source, c("generic", "agilent", "agilent.mean", "agilent.median",  : 

  'arg' should be one of “generic”, “agilent”, “agilent.mean”, “agilent.median”, “arrayvision”, “arrayvision.ARM”, “arrayvision.MTM”, “bluefuse”, “genepix”, “genepix.mean”, “genepix.median”, “genepix.custom”, “imagene”, “imagene9”, “quantarray”, “scanarrayexpress”, “smd.old”, “smd”, “spot”, “spot.close.open”

请问课程代码中 “genepix” 是否需要改？
