Unknown error in functional analysis

Hi, the bug is related to functional analysis where I uploaded my data in “A peak intensity table” module. I have 10 different data set, four of them could be processed well, 6 of them could not be “submitted”. Once I submitted in the first page, it came back as result of unknown error (I attached the pic in it).
Tamoxifen (dosage) (+) (?).csv (2.3 MB)
Tamr-1 (+) (?).csv (1.2 MB)
Lapatinib dosage (+) (?).csv (2.2 MB)
Tamoxifen (dosage) (-) (?).csv (2.4 MB)


I would suggest you to start with cleaning up file names and group labels: only English letters, numbers, underscore, hyphen are allowed.
