But again, I get a textual analysis with overrepresented words etc. (This is from an old project on single-cell gene expression.) This is a very common way to format tables in flat text files. That is, the first column consists of (one-word) ID’s the rest is numeric. Let’s give it something more standard: a tab-separated file with a header line and the other lines consisting of a cell ID in the first column followed by all numerical values. Apparently the second column is enough to throw off the system.Ĥ. The structure of the file is that it starts with two comment lines (beginning with “#”, as is the custom), after which all lines are tab separated with a numeric ID in the first column, a complex name (which can consist of several words) in the second column, followed by eight columns with numeric values (complex abundances in different sets of tissues). It was successfully imported into Wolfram Alpha, but the “analysis” I got had completely missed that it was a numeric data set, and only gave me information about word counts, character frequencies, frequency of capitalized words etc. This time I tried a table of protein complex abundance values in a certain type of cancer, something we are working on for a paper. OK, so no luck with the CSV files, let’s try a tab separated file. However, after uploading, I get the message “Wolfram|Alpha doesn’t know how to interpret your input.”ģ. This is a perfectly ordinary CSV file with a regular matrix structure, a header line, and no missing values it can be readily imported into R without errors, for instance ( read.csv(“file.txt”) works fine). A CSV file from an old data set about gene expression in neural stem cells which I used to work on. This is a bit annoying if the input isn’t looking clean, it would be more useful to get an error message telling you that the data could not be processed.Ģ. This CSV file is a bit “dirty” (lots of missing values, some rows are longer than others) so I wasn’t expecting a clean import, but what actually happens is that Wolfram Alpha Pro just gets stuck for ever, with a window saying “Processing file.csv.” I’ve tried this three times now with the same result. A CSV file that came from screen-scraping some Kaggle leaderboards for a visualization I was planning to do with Joel but which we never bothered to finish. Still: the output shown in the blog looked cool, so I tried to upload a few files, with the following results:ġ. The first letdown is that there is a 1-megabyte limit to the data upload, so I guess we can safely say that Wolfram Alpha Pro is not a “big data” thing … Joking aside, 1 Mb is really not enough to make this service anything more than a toy analytics sandbox at least for me, I would need to subsample practically all of the datasets I work with to even be able to upload the data for analysis. Now I was looking forward to those cool automatic PCA plots and linear regression auto-magically appearing upon uploading my data … So I signed up for an account at $5 a month (introductory price), I would have been willing to pay for a few months just to try it out, but as it happens, they also have a free 2-week trial which I duly activated. And then Wolfram|Alpha Pro should automatically do a whole bunch of analysis, and then give me a well-organized report about my data. And if my data isn’t too large, this should all happen in a few seconds.Īnd what’s amazing to me is that it actually works. The concept in Wolfram|Alpha Pro is that I should just be able to take my data in whatever raw form it arrives, and throw it into Wolfram|Alpha Pro. If you have any questions, please contact us.I was pretty intrigued when I read this blog post about the new “Pro” version of Wolfram Alpha, with passages like: This plan also allows for the purchase of additional Cloud Credits. If you exceed this limit, you will not be able to upload or create any new files.Īll Cloud Credits of the previous plan carry over to Cloud Basic. This plan includes 200 MB of file storage. With the Cloud Basic plan, you will continue to be able to access and edit all of your existing files. Once your paid subscription ends, your Wolfram|One, Mathematica Online or Wolfram|Alpha Notebook Edition plan will be downgraded to the free Cloud Basic level. For example, if you purchased an annual subscription plan and have three months left, then choose to stop billing, the subscription will remain active until the end of that three-month period. When you stop billing, your plan will remain active until the end of your current billing cycle. Select “Stop billing” to cancel this subscription at the end of your current billing cycle.Choose the product that has the subscription you wish to cancel.Your subscription to a Wolfram Cloud product can be cancelled through your Wolfram Account:
