If a "*" character is appended to the path, the subdirectories of the path are also searched.
Optionally, the depth of the search can be specified after the "*" character and the "<" marker.

Examples:

Search subdirectories in the patient directory:
  "D:\Images\%1\*"
  
For the patient 123456 to become all images from the directory
  "D:\Images\123456\"
and all subdirectories are returned.
  
Possible results:
 "D:\Images\123456\Img1.jpg"
 "D:\Images\123456\2010\Img2.jpg"
 "D:\Images\123456\2011\Retension\Img3.jpg"
 ...

With the path:
  "D:\Images\%1\*<1"
Only the following file will be found:
  "D:\Images\123456\Img1.jpg"
  "D:\Images\123456\2010\Img2.jpg"
This file is not found:     
  "D:\Images\123456\2011\Retension\Img3.jpg"
   
Also allowed: Search all images on the D: drive:
  "D:\*"
Please avoid, may take a very long time.

Wildcards "*" and "?" are also possible in all directory names.
Wildcards are used according to the normal Windows conventions:

? stands for a character
* stands for any number of characters

OnyxCeph³ searches for all matching paths and returns the files they contain.

For the patient Müller,Jan, for example, at the import path:

D:\Scans\Day????????\%8,%9\*<1

searches the following directories (if available):

D:\Scans\Day20160301\Müller,Jan\
D:\Scans\Day20160301\Müller,Jan\Head\
D:\Scans\Day20170313\Müller,Jan\

Only for image acquisition the following macros are supported:

"<FDK_D>": The name of the data path according to KFO Office conventions with date of birth is used. 
"<FDK_I>": The name of the data path according to the KFO Office conventions with patient ID is used.

Example: 
C:\PatientData\ is the path configured in KFO Office for patient images.
In Onyx, the path C:\PatientData\<FDK_I> would then have to be configured for the third-party programs.
( Assuming FDK uses the patient number, if birthday instead of <FDK_I> then use the macro <FDK_D>). 

"<TNTand>": SurnameFirstName is inserted without spaces (for TNTand). 

Example: Hans Peter Müller-Herbig becomes "Müller-HerbigHansPeter".

The following macros start with "<" and end with ">". They use multiple parameters separated by "|". Syntax::

<C|T|P0|P1|P2|...>
C: Macro command e.g. "SS" for SubString
T: Text, may contain placeholders like %1, the placeholders are always replaced first and 
   only then the macro is executed.
P0, P1: Parameters, depending on command different number and usage 

In general, macros may be nested. That means T, P0, P1, … can contain macros. The macros are resolved from the inside to the outside.

"<SS|T|Pos|Count>" 
A substring of length Count is returned from the text T, starting from Pos.
If Pos + Count exceed the length of the string, the string is returned starting from Pos.

Example:
  "This is a <SS|new MacroXX|5|5> in text"
turns into:
  "This is a Macro in text"

"<RS|T|SearchString|ReplaceString>" 
In text T substring SearchString is searched and replaced with ReplaceString.  

Example::
  "This is <RS|a old macro|old|new> in text"
turns into:
  "This is a new macro in text"

"<FL|T|Size|Char>" 
In the text T is filled on the left side with the character Char that T has the length Size.

Example::
Fill patient number to 8 characters with zeros:
  "ID<FL|%1|8|0>"
becomes for patient 123456 to:
  "ID00123456"

"<FR|T|Size|Char>" 
In the text T is filled on the right side with the character Char that T has the length Size

Example:
Fill patient number to 6 characters with zeros:
  "ID<FR|%1|8|0>"
becomes for patient 123456 to:
  "ID12345600"  

"<TL|T|Size|Char>" 
Im Text T werden auf der linken Seite so viele Zeichen Char gelöscht, dass T die Länge Size hat
If the last character on the left side is not Char, the T remains unchanged
  
Example:
Delete leading zeros in patient number up to 8 characters:
  "ID<TL|%1|8|0>"
becomes for patient 0000123456 to:
  "ID00123456"

"<TR|T|Size|Char>" 
In the text T on the right side so many characters Char are deleted that T has the length Size
If the last character on the right side is not Char, the T remains unchanged

Example:
Delete appended X in patient number up to 8 characters:
  "ID<TR|%1|8|X>"
becomes for patient 123456XXXX to:
  "ID123456XX"  

  "ID<TR|%1|8|X>"
becomes for patient 1234567890XXXX to:
  "ID12345667890"  

"<CL|T|Count>" 
In the text T on the left side Count characters are deleted.
If T is shorter than Count, an empty string is returned.
  
Example:
Delete leading text "ID" in patient id:
  "<CL|%1|2>"
becomes for patient ID123456:
  "123456"

"<CR|T|Count>" 
In the text T, Count characters are deleted on the right side.
If T is shorter than Count, an empty string is returned.

Example:
Delete year number in a patient ID:
  "ID<CR|%1|5>"
becomes for patient 123456-2021 to:
  "ID123456"  

"<CTX|T|Tag|Found Text|Not Found Text>" 
In the text T the text Tag is searched. If it is found, the "Found text" is returned, 
if not the "Not found text" is returned.

Example:
Check if a tag is included in the attributes:
  "<CTC|%{pat:attributes}|;CLP;|cleft palate|>"
becomes for a patient with the attribute ;ORTHO;CLP;CHIR; to:
  "cleft palate"    

"<POS|T|Tag>" 
In the text T the text Tag is searched. If it is found, the position of the first character is returned, 
if it is not found, an empty text. 

Example:
Find out at which position a tag is included in the comment:
  "<POS|%{pat:notes}|station:>"
becomes for a patient with the comment "Dr. Meier station:B5" to:
  "11"  

"<U7|T>" 
The text T converted to UTF-7 encoding  

Example:
  "Name: <U7|%3 %2>"
becomes for the patient with the name "Björn Müller" to:
  "Name: Bj+APY-rn M+APw-ller"

"<URLE|T>"
The text T is converted to UTF-8 and then escaped for transmission as a URL.
  See also: https://en.wikipedia.org/wiki/URL-Encoding

Example:
  "<URLE|Name: %3 %2>"
becomes for the patient with the name "Björn Müller" to:
  "Name%3A%20Bj%C3%B6rn%20M%C3%BCller"  

"<FILE|T>" 
In the T text, all characters that are not allowed for file or directory names are replaced.
Invalid characters are replaced (as already for the placeholder "%1") during correction as follows:
    "*" -> "~1"
    "?" -> "~2"
    "@" -> "~3"
    ":" -> "~4"
    """ -> "~5"
    "/" -> "~6" 
    "<" -> "~7"
    ">" -> "~8"
    "|" -> "~9"

Example:
  "Model<FILE|%A>.PDF"
becomes the valid file name for the patient with the model number "123\A":
   "Model123~0A.PDF"  

The integer T is increased by INCVAL. The result is also an integer.
The texts in T and INCVAL must be convertible to an integer. Negative numbers are permissible.

Example:
Increase step number %S by 8:
  "Step: <INC|%S|8>"
becomes for Step 4:
  "Step: 12"  

"<VAL|T|Tag>" 
The text T should be a multiline (e.g.: %M Notes). 
A search is made for a line that starts with the tag followed by "=", the text after the "=" is returned

Example:
Read out order number "Order" from the patient comment:
  "Order #<VA|%M|ORDER>"
If there is a line "Order=0-8-15" in Notes (merge command %M), the result is:
  "Order #0-8-15"  

"<DTF|T|FS>" 
The text T should be a date or time in one of the following formats: 
  yyyymmdd, yyyymmddhhnnss or yyyymmddhhnn

In FS a format string must be passed, according to which date (and time) are formatted. 
The syntax is described here: 
http://docwiki.embarcadero.com/Libraries/Sydney/en/System.TDateTime.FormatString

Example:
<DTF|%4|dd.m.yyyy> -> "19.9.1990"
<DTF|%X|dddd mmmm d, yyyy hh:mm:ss AM/PM> -> "Tuesday June 15, 2021 10:39:00 AM"     

 "<AGE|STARTDATE|ENDATE|FORMAT>" 
 Der Text in STARTDATE und ENDATE sollte ein Datum or time in one of the following formats:
  yyyymmdd, yyyymmddhhnnss or yyyymmddhhnn
 To output the patient age, %4 should always be transferred as STARTDATE.
 As ENDDATE, for example, "%{img:seriesdate}" or "%E" for the picture date can be transferred.
 
 The formatting of the result can be selected with FORMAT. The following values are possible here: 
 SHORT, LONG, YEARS, DECI, DAYS or YYMMDD.
 
 Examples:
 Age on the date of the session:
    <AGE|%4|%{img:seriesdate}|SHORT> -> "19.5 Years"
    <AGE|%4|%{img:seriesdate}|LONG> -> "19.5 (19 Years, 6 Months)"
 Age at the date of the picture:
    <AGE|%4|%4|DECI> -> "19.5"
    <AGE|%4|%4|DAYS> -> "7128"
 Current age of the patient:
    <AGE|%4|%{time:ansi}|YYMMDD> -> "190613"
