I/O Problem when try to make subset

Hi All,

 

I try to find specific string which ends with 452 in a column named Sample_ID and make a subset containing all rows with this string together with all other columns. I tried to write the codes as below but I got "I/O problem" and "unable to open in readwrite mode" in log.

So what is the problem here?

Can anybody help me with this?

 

Thanks

Close All( Data Tables, NoSave );

// pick data table 1
dt1_dir = Pick Directory( "Select directory for data table 1");
dt1_Name = Pick File(
 "Select data file 1",
 dt1_dir,
 {"JMP Files|jmp;jsl;jrn", "All Files|*"},
 1,
 0,

);
Show(dt1_Name); // show dt1_Name string in log
dt1=Open(dt1_Name); // reassign dt1 to data table from string dt1_Name
Show(dt1); // show data table dt1 in log to check

// pick data table 2
dt2_dir = Pick Directory( "Select directory for data table 2");
dt2_Name = Pick File(
 "Select data file 2",

Show(dt2_Name);

Show(dt2);

//concatenate two tables and concat_dt is the output table
concat_dt = dt1 << Concatenate(dt2,
       Output Table("concat data table"),
       Create Source Column
       );
Show(concat_dt); //show concat_dt data table in log
Close(dt1, NoSave);
Close(dt2, NoSave); //close both dt1 and dt2


//select specific sample_ID from concat_dt and make subset out of it
prep_dt = concat_dt << Subset(Row( 
          concat_dt << get rows where(Regex( :Sample_ID, "71MT052800452") == :Sample_ID)),
       selected columns only(0), 
       );
          
Close(concat_dt); // close concat_dt
