发帖数: 688 | 2 If you know how to import a single .gpr into R, then just add a loop on top
of it for 50 .gpr files. Of course, you need to manege data objects well in
R.
If you do not know how to deal with a .gpr file, then we can discuss it.
First let's see what the file content look like and what do you want to do
with it? |

gpr file.
If you need to write your R code from scratch to import .gpr file, it could
take some time and you'd better ask for local help. |

发帖数: 12276 | 6 我试着导入一个文件：GSM170754.gpr
library(marray)
filenames <- c("GSM170754.gpr")
data <-read.GenePix(filenames)
save(data, 'data_raw.RData')
当读入DATA的时候报错:
Reading ... GSM170754.gpr
Error in if (skip > 0) readLines(file, skip) :
missing value where TRUE/FALSE needed
多谢指教!! |

what is being used in your own .gpr file. |

发帖数: 12276 | 9 多谢各位.今天打开gpr文件只有一个COLOR,可能是因为这个没法用MARRAY读入?
SCAN可以存成.gpr,但只是单色文件.
在我印象中,CEL是单色,GPR是双色,看来理解有点错误.
