Cannot import file using the current EpiVis system

[jingjtang]

The current EpiVis system (https://delphi.cmu.edu/epivis/) does not allow importing files. At least it cannot work using Safari/Chrome/Firefox

However, this one (https://delphi.midas.cs.cmu.edu/epivis/epivis.html)) works.

That alternate link at delphi.midas.cs.cmu.edu will go way soon and eventually redirect to delphi.cmu.edu, but it is interesting that it points to a working system.

It's just that Firefox doesn't seem to give useful debug info. It doesn't work on Chromium either, but Chromium does give useful debug.

From clicking around in devtools:

• Error occurs in the "sibling" case, but for a parentless level-0 active
• There appear to be no rows recognized, which may be what prevents a level from being assigned. The (final value of the) rows variable inside importCSV seems weird: it just appears to be one long array of entries rather than something 2-D, and contains some bogus-looking entries, e.g., the 6th entry is "suscep_rateak", splicing together the last colum header and the first entry of the first non-header row. This may point to the issue being in csvParseRows or other processing done to rows + unclear error messaging when no rows are recognized inside of importCSV. [Actually, it looks like it's even earlier, where it looks like all the non-commented-out lines are concatenated together without any separator into a single lines string; I'm assuming that the split lines don't contain the "\n"s anymore.]

@jingjtang do you have a sample CSV file I should test?

@sgratzl Here it is.
