gene expression data of scRNA-Seq

Question

[jabbari.parnian]

Hi all,

I have downloaded the processed data of a scRNA-seq experiment from GEO (GSE72056). when I open the data in R, for the first column I get all the gene names instead of one gene name.

> a[1,1]
[1] tumor
23687 Levels: 1-Dec A1BG A1BG-AS1 A1CF A2M A2M-AS1 A2ML1 A2MP1 A4GALT A4GNT AA06 AAAS AACS AACSP1 AADAC AADACL2 AADACL3 AADACL4 AADAT AAED1 AAGAB AAK1 AAMDC AAMP ... ZZZ3
> a[2,1]
[1] malignant(1=no,2=yes,0=unresolved)
23687 Levels: 1-Dec A1BG A1BG-AS1 A1CF A2M A2M-AS1 A2ML1 A2MP1 A4GALT A4GNT AA06 AAAS AACS AACSP1 AADAC AADACL2 AADACL3 AADACL4 AADAT AAED1 AAGAB AAK1 AAMDC AAMP ... ZZZ3
> a[3,1]

I don't understand how I can find the gene expression value for gene A1BG, for example. Do you know how I can find the gene expression level for each gene?

Please share the command you have used to open the file in R.

[jabbari.parnian]

I used read.delim("filename")

[Arup Ghosh]

Try read.delim(file, header=TRUE, sep="\t")

[jabbari.parnian]

it's still the same...
