Hello, I want to import a .cel file into R. Under the Windows platform, i used the command "read.celfile" in the package "affyio" and successfully imported the data. However, when i turned to used R in Ubuntu and repeated the same steps, there was an error: "read.celfile("/home/bmi01/P1/1.CEL") : Is /home/bmi01/P1/1.CEL really a CEL file? tried reading as text, gzipped text, binary and gzipped binary Calls: read.celfile -> .Call" What is the problem? -- ¹ùС²¨ µ¥Î»£ºÖÐɽ´óѧÊýѧÓë¼ÆËã¿ÆѧѧԺ Óʱࣺ510275 ÊÖ»ú£º13570214302 E-mail£ºmc03gxb@126.com [[alternative HTML version deleted]]

It looks as if that file doesn't "look like" a cel file. You mentioned that read.celfile previously worked in windows, though. Did it work for *this* particular cel file that you are now trying to import under linux, or were you saying that it has just worked before on some other cel files you might have been using? -steve -- Steve Lianoglou Graduate Student: Computational Systems Biology | Memorial Sloan-Kettering Cancer Center | Weill Medical College of Cornell University Contact Info: http://cbio.mskcc.org/~lianos/contact
