please state the exact error message! As an initial guess, I'd recommend using a semicolon ( ; ) as a separator.
Please also make sure, that none of your lines of data - ends in a whitespace (like a blanc or tab), - is of different length (like due to a missing value), - is empty, - or contains the values in a different order.
Hello, I'm trying to calculate PET, PMV, SET and for that I created a text file containing: date,time,air temperature,relative humidity,wind velocity and the mean radiant temperature in the following manner - DATE,Time,Ta,RH (%),v,Tmrt 25.6.2015,06:00,30.5,58,2,34 27.6.2015,06:00,34.9,43,3,38 29.6.2015,06:00,35.5,39,3,37 01.7.2015,06:00,32.4,60,2,36
from control panel I use ',' as tab separator. Problem is that whenever I check-on the headline and put the input data file by checking off the above indicators and clicking New , after some time a message occur "Read error from datafile!(Date format?Number of columns?)".
Till now I can't figure out what might be the problem, so your reply to this message would be highly appreciated Thank you in advance for your time.
You stated that the error only occurs after some time. Did you check "Output in file"? If not, please do so and retry! If so, please check the output file for the exact line in which the error occured. RayMan always reads one line, processes it and writes an output line. Please find the input line according to the last line in the output file. The next line will be the one RayMan has issues with. Check this line for the points I stated above. If you can't fine anything that could be wrong, please copy and paste the previous line, the problematic one, and the next line all together into your reply, so I can look for the error as well.
Best regards, Dominik
EDIT: Ah, there also might be a problem with your date format: "01.7.2015" You always have two digits for the day, but sometimes only one digit for the month! Please decide for either of them!
Sir, Thank you for your kind gesture. I would like to inform you that I could not able to process a single output from the input file , it shows the error message only "Read error from datafile!(Date format?Number of columns?)". I also check for the date (month) issue but not solved yet and also I am not able to find out the option "write output to file"? Kindly help me Regards
the checkbox is called "Output in file". It is located in the lower left part of RayMan's Datafile window. For you, the form should look similar to the following (with the file selected of course):
Best, Dominik
EDIT: Your current date format is "dd.m.yyyy", not "d.m.yyyy". Strange, but could work (I tried with a small test file).
Sir, Actually I use the Rayman 1.2 version. As I unable to execute my data file with this version, please send me the link to access the Rayman Pro version. Regards
RayMan pro is the development version and can not be downloaded. It has some (partly unfinished) additional functionality, but these will for sure not affect your problem.
Best regards, Dominik
EDIT: To check your meteo input file please always view it in the Text Editor (Open with" --> "Editor"). You can see a lot of problems right there.
I have followed the advise in this post by modifying the format (d.m.yyyy and dd.mm.yyyy) but this did not resolve the issue. I have also checked Input>Datafile to ensure parameters are correct and have tried with and without Headline.
I seem to have found a workaround whereby I simply omit Date parameter and remove this column from my data
The result is an output table which looks reasonable, but with the same date entered for every row:
1 2 3 4 5 6 7
day of time sun sun Gact Sact Dact Ts Ta Tmrt PMV PET date year h:mm rise set W/m2 W/m2 W/m2 ?C ?C ?C ?C 6.7.2016 1 00:00:30 08:46:14 16:07:58 0 0 0 5.8 5.8 5.3 -4.8 -1.2 6.7.2016 1 01:00:30 08:46:14 16:07:58 0 0 0 5.4 5.4 4.9 -4.9 -1.6 6.7.2016 1 02:00:30 08:46:14 16:07:58 0 0 0 5.5 5.5 5 -4.9 -1.5 [...]
So I have 2 questions 1) Does omitting the date affect the calculations (I suspect not, but wanted to check)? 2) Can you recommend a change that might allow me to use Date if it is necessary?
the error message is a general input/output error and not necessarily connected to the date column. However, the Date col is the first one, so any general error will hit there.
How did you create the input files exactly? Did you check my first post in this thread? Seems you have a leading empty column in your first file (that needs to be removed. Also please remove the trailing whitespaces at the end of several lines in your file.)
What is "C" in your file? Cloud cover? If yes, this is redundant as you also have global radiation included. If so, please remove "C".
Secondly, "date" and "DayofYear" is redundant. Better remove "DayofYear" as date is more specific. The date you get in your last file is most probably the date from the graphical user interface and therefore always the same. Using the wrong date can lead to huge inaccuracy depending on what you want to calculate (The sun is in the wrong position!).
These data were handled in Excel and copied over into a simple text file .txt to be input into RayMan. I think reproducing the examples here might have been a bit misleading as there are no "gaps" in the actual data files (happy to email copy to you).
Yes I suspected the date is being drawn from the GUI (which is using my system to populate when I launch RayMan).
i checked the file, but is still has the two columns that need to be removed (DayofYear and C). It also uses the wrong column seperator ";", that is not supported by RayMan 1.2. Please change to tab (t).
