I can't import data #44

Closed aquiles300 closed 3 years ago

aquiles300 commented 3 years ago

I am trying to import MALA GPR data (*.rd3 format) through

library(RGPR) x <- readGPR(dsn = "erickprueba250mhz10.rd3")

but I got

Error in matrix(NA, nrow = npt, ncol = ntr) : invalid 'ncol' value (too large or NA) In addition: Warning message: In strsplit(headRAD[i], ":") : input string 1 is invalid in this locale

I dont know what is wrong with that. I am sending the files, if you can help me with that.

erickprueba250mhz10.zip

Thank you very much for your message, Marcel. It is hard to say what is the problem. I will have a closer look at your data and I hope to be soon able to solve this issue. Thank you for your patience. Best, Emanuel

In the mean time, could you please show me the output of your session info:

Thank you.

Thank you Marcel I could identify the problem: the encoding of the text file "erickprueba250mhz10.rad". It would be too complex to fix this issue in RGPR because it could have side effects that I am not yet aware of them. My suggestion: simply open the file "erickprueba250mhz10.rad" in a text editor and save it with encoding UTF-8 (without BOM). In windows, I recommend you to use Notepad++ (ask google how to change the encoding, it is straightforward). Let me know if it solve your problem.

Let me know if you have any question, suggestion or feedback.

Best,

Emanuel
