Complex merge files

[Carlos Renato]

Dear friends list

A total of 1000 interviewers typed their data and each generated a file in txt format. All files are separated by tabs with the variable name at the top. The problem is that there was no rule on the naming of files and each gave a different name. For example:

Clark.txt
Myllena.txt
interview.txt
w.txt

My problem is to import all these files and perform the merge of them automatically via a macro. Any suggestions? I'm working on it this Friday. If the files were standardized name no problem, solve the macro below.

For example if I want to do the merge of 1000 files each with a part of the name in common, located in the c: \ spss:

file1.sav
file2.sav
file3.sav
.
.
.
file1000.sav


/ * Perform the merge any number of files as long as they have the same variables.
DEFINE MacroMergeAllFiles (DiretorioComum=!TOKENS(1)/ NomeComum=!TOKENS(1)/ QtdeArquivos=!TOKENS(1))
!DO !FILE= 1 !TO !QtdeArquivos.
!IF (!FILE=1) !THEN
GET FILE= !DiretorioComum+!NomeComum+"1.sav".
!ELSE
ADD FILES /FILE=*
 /FILE=!DiretorioComum+!NomeComum+!QUOTE(!FILE)+".sav".
EXECUTE.
!IFEND.
!DOEND.
!ENDDEFINE.

/*MacroMergeAllFiles DiretorioComum='C:\spss\' NomeComum='file' QtdeArquivos=1000.

The problem is to perform the same procedure but with different file names.

Thanks for all.

if you are on a windows system do something like this untested procedure  It is what we did before there was PYthon.
put all the .txt in a folder e.g. c:\temptxt
open the command window
md c:\alltxt
cd c:\temptxt
copy *.txt c:\alltxt\combo.txt

read combo.txt into spss with all fields tab separated strings
do if $casenum eq 1.
compute source =1.
else  if  varname1 "whatever".
compute source source+1.
else.
compute source = lag(source).
compute keepit = 1.
end if.
select if keepit eq 1.
* this may be a rare instance where you might need this execute.
execute.

* before there was alter type we wrote the data out as text and read it in in a new format.

*see the help for alter type you might be able to use 'all' as the variable list.
alter type id (f8) v1 v5 (f2) v2 to v4 v6 to v99 (f1) v100 (adate10).
* I have not tested what happens if a string variable is altered to a string variable to make your variable list more complete.
*you can use several alter type command one kind of specification shortens strings to the longest string necessary for that variable.

This way you can eliminate many warnings.

Since you are doing these one at a time, you will make a lot of data passes, but if the files are not huge this will not matter.
The easiest way to do this task would be to use the SPSSINC PROCESS FILES extension command from the SPSS Community site (www.ibm.com/developerworks/spssdevcentral).  This command processes all the files in a given location, optionally matching a wildcard expression.  It runs a batch of syntax that you specify over each file.  It defines file handles and macros that you can use in the syntax job.  the command appears on the Utilities menu as Process Data Files.

Hi Carlos,

If you wish to use traditional macros, you can go this way:

1. Create the list of all file names. Under Windows, you can e.g. create a text file named "list.bat" containing this line:

   dir *.txt > list_of_files.dat

By runing the bat (doubleclick), you get the list in the file list_of_files.dat. Open it in MS Word and extract the names of files (use a proportional font and select rectangular blocks by keeping Alt key while working with the mouse).

2. Then process the list as an argument of the macro cycle !DO !varname !IN (list)

(Otherwise use Python, see Jon Peck's post.)

Best regards,

Jan

Friends

Thank you so much for all the answers. I will address all suggestions. All are great.

Jon,
Does that extension command include a way to include a variable that specifies the source file for a case? Identifying the source helps track down data anomalies. Also, unless the data files are proofread or double-entered and compared at the source, QA needs to be done by the receiver.  The source id needs to be done in a consistent way so that keyings/enterings can be paired.

The procedure runs one file at a time.  The generated macros and file handles do identify the input file, mainly so that the code can generate an output file based on the input name in typical usage, but the syntax being run is anything you want.

Here is an extract from the help.

The syntax file will be invoked for each input dataset. It should read the file and carry out any desired operations. File handles and macros are defined to refer to the input file and various output locations. The file handles are as follows.

• JOB_INPUTFILE: The input file.
• JOB_DATADIR: The input data directory
• JOB_OUTPUTDATADIR: The specified output data directory or <NONE>
• JOB_VIEWERDIR: The specified Viewer output directory or <NONE>

• For a SAV file you could read the data with the command
GET FILE="JOB_INPUTFILE".

• Macros are defined with these same names except starting with "!". Two additional macros are defined.

• !JOB_DATAFILEROOT: The name of the input data file without its extension
• !JOB_DATAFILEEXT: The extension of the input data file

Dear friends

In Windows:

- Select all files in the dir using CTRL+A
- Next press F2 and rename one file, for example, rename for DATA.
- the effect is propagated to the other system files and rename all adding an index in brackets.

DATA (2).DAT
  .
  .

DATA (100).DAT

Using the macro below, we can merge all files in this format.
