Defining a workflow for importing the RNA-seq count data - r

Question

i am getting starting with R and i read some basics and syntax to get me started with it,
now i using miodin to define a project and a case-control study design.
library(miodin)
mp <- MiodinProject(name = "MyProject", author = "Myself", path ="." )
mshow(mp)
I have a file named "randseq"in my computer hard-disk which look like this.
ID LineA_1 LineA_2 LineA_3 LineA_4 LineA_5 LineB_1 LineB_2 LineB_3 LineB_4 LineB_5 LineB_6 LineB_7 LineB_8 LineB_9
ENSG00000000003 23 1 0 0 0 1 0 0 0 0 0 3 3 0
ENSG00000000005 0 0 0 0 0 0 0 0 0 0 0 0 0 0
ENSG00000000419 0 0 0 0 0 0 0 0 4 0 0 0 0 0
Now i want to define a workflow for importing the RNA-seq count data of that file which is in a folder named analysis_with_r, using the study design. Execute the workflow and export the dataset to the project folder. Below is my code for it
mw <- MiodinWorkflow(name = 'MyProject')
mw <- mw + downloadRepositoryData(
name = 'RNA downloader',
accession = 'randseq',
repository = '/Users/aarf/Desktop/analysis_with_r/randseq.txt',
path = 'data',
type = 'processed'
)
mw <- insert(mw,mp)
mshow(mw)
mw <- execute(mw)
saveDataFile(mp)
export(mp, 'dataset', 'randseq')
After running this code i get this error
[INFO] Module terminated with the following error [ERROR] Unknown
repository/Users/aarf/Desktop/analysis_with_r/randseq.txt
[INFO] 1 modules were not executed [STATUS] Execution finished
Can anybody tell me what am i doing wrong here?
