The death data file for the Corona Virus is in the above format. I had a small play with the data in C# but run into graphing problems, I am translating the program into Fortran - there appear to be some interesting features in the FFT of the data, which I hope to publish to help the health stat people.

Does anyone have a good idea for reading the line and then taking apart into

21/03/2020 -- ignore

21 integer to 0 on first line all integers the name is different character length, CV is usually only 2 chars and the population is an integer, but is pop missing from the JPG line and the id is not two characters.

There is a new file every day

Regards

John

As a CSV file, you could read the whole line as a text string and parse it to find each field and unpack into the appropriate variables.

10/03/2020,10,3,2020,-9,1,Cases_on_an_international_conveyance_Japan,JPG11668,

You will have to deal with the Geold field not being 2 characters, and missing Pop_Data.2018

My guess is JPG11668 refers to a different file and/or record in file, and/or different region (island) of Japan. This data will have to be obtained elsewhere.

Edit: found this

In the above mentioned link, they do not investigate (plot) infections/deaths per 100,000 per day.

The charts listed are of minimal value. you will need to get the population figures for Japan seperately.

This does not work as expected -- the af does weird things -- help --

JohnNichols · ‎03-27-2020

Found error apologies -- need to actually call subroutine

jimdempseyatthecove · ‎03-27-2020

In the file you uploaded, the header line reads:

DateRep,Day,Month,Year,Cases,Deaths,Countries and territories,GeoId,Pop_Data.2018

So af will never match "da" or "DA" as it has "Da" at beginning of line.

Jim Dempsey

Jim:

Thanks -- if read the line in and use the equalivanece statement to match the first two characters on the first line. These people change the file a lot and I am trying to make it as robust as possible. That is a mecej4 trick, not mine.

I found a trick of looking for the markers using a series of if routines

it is working so far.

I am almost there with the read then setting up the structure

I should have kept my mouth closed and not said - this looks interesting

This program is tripping my virus program - Microsoft defender

Can someone try it and see if is just my machine --

JohnNichols · ‎03-27-2020

It appears to be the manifest file, is it safe to turn it off

jimdempseyatthecove · ‎03-28-2020

John,

Add arrays for:

DateRep, Day, Month, Year, Cases, Deaths, Countries_and_territories, GeoId, Pop_Data_2018

Read the file line by line (no equivalence)
Use the comma as a separator to extract each field and insert into each field into its respective array
note, some lines end in , leaving the last field blank.

This data file is not fixed field. don't assume the Geold is 2 characters. I saw that the data file may have an exception with a 3 character code.

RE: Microsoft Defender

Check the Document. See if there is an exclude folder option, I use Avast and it has this option.

JohnNichols · ‎03-28-2020

Jim:

Thanks for the notes. It has been interesting, I have swapped computers, deleted Intel , VS and done a lot of reinstalling with different versions of VS and Fortran.

The error continues to occur in all combinations.

So I have been back through and added line by line and tested at eaxh step. There appears to be a problem with

            if((iline(loc+5:loc+5) .eq. ',')) then
                read(iline(loc+1:loc+4),210)name2
                nameA = name2
210             format(A4)
            elseif((iline(loc+6:loc+6) .eq. ',')) then
                read(iline(loc+1:loc+5),220)name5
                nameA = name5
220             format(A5)
            elseif((iline(loc+7:loc+7) .eq. ',')) then
                read(iline(loc+1:loc+6),*)name6
                nameA = name6
230             format( A6)


            end if

The read(iline(loc+1:loc+6),230)name6 causes the virus error on both VS which will not run the program if I change the * to 230 and from Defender.

I am not sure if it is a bug or a code error.

The CV.zip has the current iteration.

I have to check the output files once I am finished to catch all the oddities in the data file. US Virgin Islands causes a strange output. But I want to solve this problem first.

Thanks for the help

John

You can fancify that if you want: additional error checking, pick nth argument from line as text or integer (or real or double), etc...

JohnNichols · ‎03-28-2020

The underlying FFT causes the 0.8 -- it is interesting - the line is fully about the line for the last 10 days

Teh Europeans changed the file format again today -- got to love them.

mecej4 · ‎03-28-2020

You displayed a plot in #16 and your subsequent comments refer to the same plot. Unfortunately, you did not tell us what the abscissa and ordinate variables were.

Does FFT mean 'food for thought' or 'fast Fourier transform'?
