Hi everybody
I am trying to import a commuting time matrix (231x231) done in Qgis to use it instead a contiguity matrix in order to make the spatial analysis not based on distances but on time. However, when I arrive to the step "spmat import SPWMat using SPWMat.txt, replace normalize(row)" I have as error message: "Error in line 1 of file D:\Olarte\Documents\Pour_OrbiGis\distanceW_e2.csv" . I thought it was because of the type of the variables but it seems it is not the cause. Can you please help me? I am trying for two days to make this but I couldn't find the solution so if you can help me I will deeply appreciate of that.
All best,
it would help to see your .csv file, but even without seeing it, I wonder if the first line is a header "alphanumeric" fields for the names ... that would cause problems if the import routine is expecting numerical data; in MATLAB importing such a csv file would allow us to specify whether or not the file has as header
Thank you M. O'Kelly
Actually, my file has not "alphanumeric" elements so I don't understand why I have this problem. If you want, I can send to you the csv file. The data come from a GIS program (Qgis) but are on csv format.
Thank you again
I forgot to tell you
The first line is a header with no "alphanumeric" fields for the names but numerical data. Each "region" has a numerical code.
Hope you can help me and once again, thank you for your response.
All best,
Carlos O.
sure --- I can take a look at the file; no promises but at least we can see if can be opened and maybe translated -- my e-mail is [email protected]
Hi Carlos,
I have a solution for you.
Open your csv has a data file and then use the spmat dta to import the dataset as a matrix. For example:
spmat dta distmat Mindist*, id(ID) replace
let me know if it help your you need more detailed information
best,
Rita
