I have a my_text.txt file and the next e file in the same directory:
extend my_unit {
run() is also {
for each line in file "my_text.txt" do {
// ...
};
};
};
I get the next run error:
*** Error: No match for file 'my_text.txt'
Why do I get the error? How the for loop over all lines in a text file should be used?
Thank you for your help
The file name is looked for relatively to your working directory (from which you run Specman), not relatively to the source file in which the code is written.
It does consider SPECMAN_PATH, but probably your SPECMAN_PATH does not point directly to that directory.

I want to be able to create a new file and write a string into it. Examples that I can find all seems to pertain to writing to an existing file.
String fileName = 'myFile.txt';
String contents = 'hello';
void writeToFile(String fileName, String contents){
File outFile = File('content://com.android.providers.media.documents/document/document/document_root/' + fileName);
outFile.writeAsString(contents);
}
This results in the following error, as expected
Unhandled Exception: FileSystemException: Cannot open file, path = 'content://com.android.providers.media.documents/document/document/document_root/myFile.txt' (OS Error: No such file or directory, errno = 2)
How can I create a new file in which I can write my contents?
Are you sure that the path exists? writeAsString does create the file if it doesn't exists, but it doesn't create the full folder structure up to the file you're trying to write to. Also, you might not have the rights to write in the path you've specified.
Anyway, you'd better use this plugin to get the folders' path instead of hard-coding them.
I imported my excel file into R Environment and saved the path by creating a new file in R scrip. However, when I tried to check my directory and load the dataset, I received the following message " Error: path does not exist: ‘MIS_655_RS_T3_Wholesale_Customers’
What am I doing wrong here?
Thanks
Have you missed the format of your dataset, eg. csv, xlsx.
I suggest you first set your file as working directory, then the following code might help you with it.
Dat_customers <- readxl::read_excel("MIS_655_RS_T3_Wholesale_Customers.xlsx")
When I am trying to read many h5 files in one shoot. There is an OS error states like this:
OSError: Unable to open file (unable to open file: name = '/scratch-lustre/hpc-0227/deepcpgData/c{1,2,3,4,5,7,9,11,13}_*.h5', errno = 2, error message = 'No such file or directory', flags = 0, o_flags = 0)
I am sure all of these files exist and files' name corresponded with c{1,2,3,4,5,7,9,11,13}_*.h5 rightly. I am also using absolute path. My bash script looks like this:
data_dir="/scratch-lustre/hpc-0227/deepcpgData"
train_files="$data_dir/c{1,2,3,4,5,7,9,11,13}_*.h5"
It works when I use the full name of a single file, for example, c16_1572864-1605632.h5. However, I need to read a lot of files. So I have to read them in one round. I have searched many other answers but none of them deal with multiple files and the os error at the same time.
I am relatively new to the world of coding, so I am having trouble resolving an issue when running TranslocWrapper.pl tutorial_metadata.txt preprocess/ results/ --threads 2. I am trying to run the HTGTS Pipeline according to this GitHub project. This is the full error:
. Library Genome Chr Start End Strand
1 RAG1A_SRep2 hg19 chr11 36594878 36595030 -
Metadata error: chr must be valid at /home/micah/transloc_pipeline/bin/TranslocWrapper.pl line 285.
main::check_validity_of_metadata('HASH(0x2903ac8)') called at /home/micah/transloc_pipeline/bin/TranslocWrapper.pl line 248
main::read_in_meta_file() called at /home/micah/transloc_pipeline/bin/TranslocWrapper.pl line 90
I have already double-checked the successful installation of the Software Dependencies, so everything should be all good, but I am having trouble interpreting the "Metadata error: chr must be valid at ..." line. If it helps, these are the specific lines that are being called in the error:
TranslocWrapper.pl line 285:
croak "Metadata error: chr must be valid" unless grep { $_ eq $expt->{chr} } #chrlist;
TranslocWrapper.pl line 248:
check_validity_of_metadata($expt);
TranslocWrapper.pl line 90:
read_in_meta_file;
Thanks in advance for the help!
So the error is saying that one of the sequence characters in the metadata file is not present in the sequence's assembly file.
Given that this is the provided example you should assume that the data is correct and your invocation is faulty.
Have you done the TranslocPreprocess.pl preprocessing steps?
If you have try looking at the first line of the metadata file, identify the assembly entry. Ensure that the assembly file exists and that it contains the required sequence.
One common problem with this kind of code is the case of the filenames. The examples are designed to be run in Linux where filename case matters. Windows likes to pretend that case doesn't matter, this can cause problems. If you are running this code from Microsoft Windows or extracted any of the archives from within Windows this is a likely cause of the error.
I need to write a program where I run a set of instructions and create a file in a directory. Once the file is created, when the same code block is run again, it should not run the same set of instructions since it has already been executed before, here the file is used as a guard.
var Directory: String = "Dir1"
var dir: File = new File("Directory");
dir.mkdir();
var FileName: String = Directory + File.separator + "samplefile" + ".log"
val FileObj: File = new File(FileName)
if(!FileObj.exists())
// blahblah
else
{
// set of instructions to create the file
}
When the programs runs initially, the file won't be present, so it should run the set of instructions in else and also create the file, and after the first run, the second run it should exit since the file exists.
The problem is that I do not understand new File, and when the file is created? Should I use file.CreateNewFile? Also, how to write this in functional style using case?
It's important to understand that a java.io.File is not a physical file on the file system, but a representation of a pathname -- per the javadoc: "An abstract representation of file and directory pathnames". So new File(...) has nothing to do with creating an actual file - you are just defining a pathname, which may or may not correspond to an existing file.
To create an empty file, you can use:
val file = new File("filepath/filename")
file.createNewFile();
If running on JRE 7 or higher, you can use the new java.nio.file API:
val path = Paths.get("filepath/filename")
Files.createFile(path)
If you're not happy with the default IO APIs, you an consider a number of alternative. Scala-specific ones that I know of are:
scala-io
rapture.io
Or you can use libraries from the Java world, such as Google Guava or Apache Commons IO.
Edit: One thing I did not consider initially: I understood "creating a file" as "creating an empty file"; but if you intend to write something immediately in the file, you generally don't need to create an empty file first.
