    loading custom annotation on topgo

    Hi,

    I'm stuck on loading my customize annotation on topgo using R. I have a .txt file containing list of genes and their GO Ids.

    Genes Gene ontology IDs
    c10020_g1 GO:0047021; GO:0019369; GO:0004090; GO:0019371; GO:0005829; GO:0017144; GO:0030855; GO:0070062; GO:0055114; GO:0016655; GO:0050221; GO:0044281; GO:0042373
    c10035_g1 GO:0005524; GO:0016887; GO:0005929; GO:0005737; GO:0030286; GO:0005874; GO:0003777; GO:0007018; GO:0005515
    c10052_g1 GO:0005737; GO:0016021; GO:0008168

    When I tried to upload this to topgo, here's the error message:

    > geneID2GO <- readMappings(file = ".../Htub_gene_list_complete_annots.txt", sep="\t")

    Error in `[.data.frame`(a, , 2) : undefined columns selected
    In addition: Warning messages:
    1: In read.table(file = file, header = header, sep = sep, quote = quote, :
    line 1 appears to contain embedded nulls
    2: In read.table(file = file, header = header, sep = sep, quote = quote, :
    line 3 appears to contain embedded nulls
    3: In read.table(file = file, header = header, sep = sep, quote = quote, :
    line 4 appears to contain embedded nulls
    4: In read.table(file = file, header = header, sep = sep, quote = quote, :
    line 5 appears to contain embedded nulls
    5: In scan(file = file, what = what, sep = sep, quote = quote, dec = dec, :
    embedded nul(s) found in input


    I can't figure out what is wrong? Can somebody help me. thanks!


    Best,
    Christine

    Hi again,

    I loaded the custom annotation successfully, however when I tried to load my list of DEGs with Pvalues, I again encountered an error


    DEGs PValue
    c33534_g1 2.61E-239
    c52364_g1 3.60E-211
    c57190_g1 2.24E-178
    c56306_g1 2.17E-175
    c52707_g1 7.61E-182
    c49291_g10 3.08E-154
    c53016_g2 1.03E-169

    > AvsB <- read.csv("/Users/mmbl/Desktop/Htub_edgeR_filtered_AvsB.csv", header = TRUE)
    Error in read.table(file = file, header = header, sep = sep, quote = quote, :
    duplicate 'row.names' are not allowed
    In addition: Warning messages:
    1: In read.table(file = file, header = header, sep = sep, quote = quote, :
    line 1 appears to contain embedded nulls
    2: In read.table(file = file, header = header, sep = sep, quote = quote, :
    line 2 appears to contain embedded nulls
    3: In read.table(file = file, header = header, sep = sep, quote = quote, :
    line 4 appears to contain embedded nulls
    4: In read.table(file = file, header = header, sep = sep, quote = quote, :
    line 5 appears to contain embedded nulls
    5: In scan(file = file, what = what, sep = sep, quote = quote, dec = dec, :
    embedded nul(s) found in input

    It says that i have duplicates in row.names, but Im sure that the genes are all unique.

    thanks,
    christine

      Help solve problems for the next ones

      Hello tinguzman
      Since you figured out by yourself how to fix the first problem would you mind sharing
      your solution ? I just encountered the same issue and was a little bit disappointing that
      you managed to fix it but you don't tell us how.
      cheers

        Nine Things a Sample Prep Scientist Thinks About Before Sequencing
        by SEQadmin2


        I’m not a sequencing expert. I’m a purification scientist who uses NGS to evaluate workflows my group develops. With this perspective, we think about the sample first and the NGS workflow second. The sequencer is an exceptionally honest reporter, but it can only report on what you give it, so whether you get clean, interpretable data from an NGS workflow is largely determined before you begin.


        Here are nine questions we think about, in roughly the order they matter, before...

        From Collection to Sequencing: Why Sample Preparation and Preservation Define Sequencing Data
        by SEQadmin2


        Data variability is still an issue in sequencing technologies despite the advances in reproducibility and accuracy of these platforms. But the problem does not originate in the sequencing itself, but in the previous steps, before the sample reaches the sequencer.


        The first step is collection, followed by preservation and sample preparation for analysis. Most scientists overlook those steps, but not being careful might just be skewing the experiment’s results.
