Developers

Hi All,

Using ATLAS, new Patient Level Prediction analysis created. Now i downloaded the prediction_study.zip package from ATLAS.

When I run the prediction using Rstudio, i am getting error.

In the console its shows this error

“No plpData - probably empty cohort issue
Patient-Level Prediction Package version 3.0.10”

In the log file:

2020-08-18 20:39:29 [Main thread] TRACE PatientLevelPrediction 3 Error with getPlpData:Error: Error executing SQL: cannot change working directory An error report has been created at D:/atlas_prediction/errorReport.txt

the most cases of the “cannot change working directory” in my experience, there was a typo or unclear directory in fftemp directory setting.

Hi Chungsoo_Kim,

Thanks for your reply. Actually in the CodeToRun.R, I set the options(fftempdir=“./cache”), Initially i thought the code will create this folder automatically. After your reply, I create cache folder manually, now i am getting different error. Can you please advise, have you faced this error

please advise, thanks
Chidam

Hi Chungsoo_Kim,

Thanks for your advise. Now i am using full path in the script.

In the R console. No error.

But its not generating report. In the log files, it shows different error

Please advise if you have any experience in this error.

thanks in advance
