Most of the data mining algorithms accept two TEXT files as inputs
One file has the data matrix, and the columns are separated by either TAB (file suffix: tsv) or comma (file suffix: csv):
| |
| |
SampleID1 |
SampleID2 |
SampleID3 |
SampleID4 |
| Feature1 |
value11 |
value12 |
value13 |
value14 |
| Feature2 |
value21 |
value22 |
value23 |
value24 |
| Feature3 |
value31 |
value32 |
value33 |
value34 |
|
|
And the class labels of the samples are defined in a separate file.

| SampleID1 |

| SampleID2 |
N |
